Subject: Rustpuppy goes to Town.. No cheese with the whine..
Date: Thursday,

The trip
to town went well. I stopped at
the saw shop to see Chris and show off Rustpuppy a little.. His helper wasn’t at the shop so
Chris couldn’t go for a ride..
Then after the mundane chores
(groceries) I stopped at Jeff’s office. I have been aggravating Jeff since 1980.. He put his kid in charge of the
office and piled his bulky bod into Rustpuppy.. (he weighs over 360lbs.. I am a lightweight at 296..) Between us we were the equivalent of
almost 5 people..
Anyway after we got away from town, and I could show off a little, his
responses were as follows..
Launch-- Holy Shit!!
1-2
shift- Holy Shit!!
2-3
shift- Holy Shit!!
I guess
he was too stimulated to be creative..
With
Jeff in the car the traction in first was much improved.. I could barely spin the tires at
all... Hmmm.. On some tracks it may be
worthwhile having a passenger..
Mebbe a smaller one..
I am a
little concerned about the whining coming from the new axle. It is very noticable at certain rpm’s
like there is a resonance in the system..
I think
the hocky puck like polyurethane front eye bushings on the rear springs
combined with the hard polyurethane spring pad adds to the noise transmission
to the floorpan. And guess what I
have riveted solidly to the floorpan almost right were the spring mount
attaches.. A nice resonant
piece of aluminum.. Hmmm..
I notice
that since I took the carpet and pad out of the Suburban the 10 bolt in there
whines a little at certain speeds too..
I am
stilll going to do some recording of the whine and mebbe get with Wade (the
axle builder) about this issue..
Ol’
Rustpuppy ran flawlessly today..
The only detail is a little roughness in the motor above 5600rpm.. I suspect the bone stock Delco 1977
truck HEI just ain’t cutting it above 5500rpm..
Now that
it is test and tune time I think I will transplant the high voltage coil off
the Proform distributor and see if that makes a difference..
I am not
sure that the front shocks on Rustpuppy even need replacing.. On the bumpy back road to my place the
shocks seemed to be working just right..
Hmmm... That just
leaves the camber fine tune and the neutral interlock switch wiring.. And the trunk battery hold down bolts,
and the main battery disconnect..
And a ton of body work..
And the
whine recording and investigation..
Tomorrow
is another day..

come..

I
couldn’t hold myself back so I dropped everything in the office and got
Rustpuppy back on the road..
On the
southbound run everything was perfect, the weather fine, the road fast, the wind
still, everything but...
Nother
damn but.. Rustpuppy was not
quite up to race operating temperature from the easy 2 mile downhill trip to
the head of Rustpuppy Run..
So there
was a hesitation at launch. Not a
bog.. Just a drawn out
hesitation... Damn.. After that
Rustpuppy took off like a scalded cat..
But the results of the Southbound run was a little disappointing.
Remember
though, no tuning has been done yet..
That is a starting point..
I went up
to the private turnaround.. Ever
since I got caught up in the herd of rollers I have been shy about turning
around at the rest stop.. I
was calm and clearheaded and felt confident.. But the best laid plans.. I was a little hurried to
stage since there was following traffic and I had very little time.. The launch was perfect
though with the front and rear of Rustpuppy eagerly leaping into the air as
both rear tires spun about 1 ½ revolutions..
But
there is another damn but...
There was some uneveness in the pavement since I was staging about 100
feet up from the best spot and the traction was messed up. With the posi axle when one tire
lost traction the rear jogged to the right with alarming speed.. Since I was on the causeway and there
was no room for this kind of foolishness I let up on the throttle
instinctively.. And naturally the
damn TH350 upshifted because I had signaled with partial throttle.. Poop..
I stayed
on it but the run was a dismal 14.26@102.3..
And the
wind was picking up and the dew
forming so it was time to go home..

No real
tuning today but I spent some time on the road with Rustpuppy to record the
axle whine I have been bitching about.
I promised Wade that I would send him a recording today. That is not what is attached to this
message.
While I
was fooling around I thought it would be fun to share the sound of Rustpuppy
going through the gears a bit. I
made one run with the recorder on
and started very sedately to prevent the insane wheelspin I get on the
weathered and traction free section of the old highway where I was fooling
around.
Here is the
sound of the Rustpuppy taken from the passengers headrest. I am shifting at 5800rpm and as you see
I run out of road just after the 2-3 shift..
Based on
the rpm I think Rustpuppy gets up to a little over 82mph in the recording.

There
was a break between the cold spring rains
(actually winter with ice last night) and I got a chance to dig into the
neutral/park safety switch wiring.
After looking everywhere except under my nose I eventually found my
terminals and crimper kit. It
seems like I spend most of my time aimlessly wandering around looking for
stuff.. I must be getting
old..
Using
the great instructions from Scott Windle I easily located the switch on the
steering column and the two plugs were out in a jiffy. In t&t3-1.jpg the white thing on
the top of the steering column is the switch. the fat and lean harnesses are hanging below.. I am just going to hook up the safety
switch. It r&t3-2.jpg
you can see there is less than 3 feet to connect up.
According to the Hurst ProMatic instructions the front
switch is the neutral and park job and the rear one the reverse one for the
backup lights. My ProMatic
came with no wires and no connectors..
Mr.Gasket is saving money I guess..
The GM
connector worked good with standard male Faston terminals.. (t&t3-3.jpg)
The El Cheapo switches (not even tin plated) required the
miniature low current terminals..
I had to bend and tighten up a couple of standard Faston female
terminals to connect to the cheap switches.
Eventually
they were on and working good. I
need to come up with some kind of cover for the wires now.. (t&t3-5.jpg and t&t3-6.jpg)
More to
come.. Going to swap the HEI
coils if I have time before the rain starts back up..

The day
seemed young after finishing the wiring job. (daylight savings time probably had something to do with
that) And it wasn’t raining
yet..
So I got
into the HEI coil swap job..
Took a
picture of Goody with the old coil..
You can barely see it back there. (t&t4-1.jpg) Here is an interesting thought. Chevy put the distributor in the rear
with the hinges of the hood. Ford
tried to do better but blew it.
They put the distributor in the front with the hinges..
The
distributor cap is probably about 15 years old and the coil is the original one
from 1976.. (t&t4-2.jpg) The high voltage harness was off
in a jiffy.. (t&t4-3.jpg)
T&t4-4.jpg
shows the wiring to the distributor cap.
The triple connector is the harness to the distributor the thick pink
wire is the ignition and the skinny green one is the tach.. That old Delco cap still looks
good after 15 years..
Then the cap and coil assemblies pass on the little red stool. (t&t4-5.jpg)
The new cap adds a bit of color to the engine
compartment.. (t&t4-6.jpg)
T&t4-7.jpg
shows the finished job.. Didn’t
even have to mess with the timing..
It is tricky to get to the rear cap latch. I have to peek behind the hood holding the cable harness to
get a peep hole. Usually I don’t
bother with that and just loosen the hold down bolt so I can turn the distributor for access.. This time I wanted to just change the
coil and leave everything else alone..
For testing purposes..
The last
picture shows the old coil cover. (t&t4-8,jpg) I wonder if they are still called Delco-Remy? I bet they are not..
The coil
swap only took about 15 minutes so I had time to crawl under Rustpuppy and
tighten up the bolts on the probe and drogue exhaust flangeup. The one on the drivers side (Orville
and Mary Elizabeth) had loosened to the point of making the exhaust pipe bang
on the driveshaft loop when Goody was idling in gear..
I used a
¼” drive socket and rachet both for access and to prevent overtightening the
flanges and bending them..

In spite
of dire predictions the weather cleared up last night and it got really
cold.. (30’s) and today dawned
bright, clear, very dry, and cool..
Perfect race weather..
I was
physically challenged by the abrupt changes in the weather and could not walk
very well today but I pressed on regardless..
I met up
with my UPS man Mark just before taking off and he stopped for lunch down at
the beginning of Rustpuppy run’s north end and so I had an audience for the
first run of the day. I was
trying to do too much.. Had the
Vaio hooked up to record the run and was fooling with the G-Tech plus I was nervous
about traffic showing up on the staging area.. So I botched all of the tech stuff but paid attention
to the driving.. The run seemed
much better than any before but with too much wheelspin off the line. The southbound run staging area has a
much older and more weathered surface than the northbound.
A little
later I tried again, this time northbound and still had too much
wheelspin.. I got the G-Tech time
that run and it was bad.. 14.36@102.9.. There was something screwy with the transmission too like it
hesitated before getting all the way down to low and then hit so hard that the
wheels spun madly. Like a neutral
drop.. I have to look into
the shifter adjustment.. I
found later if I do a tiny burnout and listen for the first gear whine I can be
sure of a clean start.
There is
lots to think about.. And
not much time for fooling around since you are sitting in the middle of the
main highway in the county.
Remember
I have been waiting to test the new high voltage coil (Proform unfortunately)
that was swapped in. I had
seriously important business in town so got to town and took care of it
all. I even got to give Chris at
the saw shop the ride I promised.
He is a rodder and thought the 120 foot two wheel fishtailing burnout we
did down at the Hunter Creek road was very cool. (new nice pavement with two aboard.. I even was impressed)
Rustpuppy
is idling better, starting better, and seems much stronger all through the
power band.. It was a good
omen..
On the
way home I tried another northbound run but the wind was picking up and I got
the tranny foulup and did not complete it.. The gusty crosswind on that
causeway makes me very nervous. I
will wait till later after the wind dies down and the road is cooler.. The sun has been baking it all day..
Later
and cooler came quickly and I set out for another attempt. I took the old road south to below the
beginning of Rustpuppy run doing practice starts and messing about with the
first gear drop thingie.. I think I have it figured out but I still will check
the shift cable adjustment.
Got to
the highway. There was no
traffic. The wind had died to
nothing.
It was
cool and sunny.. It was time
to boogie..
The run
went perfectly. Good start. Tracking straight. No traffic. No
mistakes. The sun was shining on
the G-Tech so I could not see the signal for the end of the quarter so I stayed
on it till I felt Rustpuppy go up on her toes.. That is the 115mph signal so I knew it was way over.
The pictures
show the result.
I was so
excited (like a little kid) that I left Rustpuppy idling and got the video cam
to record the G-Tech reading..
Then I just sat in the running Rustpuppy for a while because I knew if I
turned the motor off the pretty numbers would go away..

A
serious cold front is moving in and the temperatures are down. It is still dry so I took Rustpuppy for
a run in the coolness. I figured the
low temp is worth some horsepower and she always ran better in cooler temps.
At first
on the trip south on the old highway I didn’t really notice that something was
wrong. I was concentrating on the
job ahead..
Then
when I did the first staging and launch practice. It hit me. Something was seriously wrong. The TCI converter would flash to 2800
and then stick at 2600 as Rustpuppy leisurely took off. It was like driving a Dynaflow
Buick. The rpm stayed at 2600 from
zero up to over 50 mph..
What the
hell?
Some
testing and fooling around and I found that Rustpuppy now had a 1 speed
transmission. Just drive.. Reverse worked but 1st
and 2nd were completely gone.
Looks
like saying nice things about the BLC’s car has shifted some bad mojo my
way. Remember the neutral drop
thingie. What was happening was
the tranny was starting out in 3rd and then finding 1st
later. Now it wasn’t finding 1st
at all, or 2nd..
Damn..
Interesting
that with the high stall converter Rustpuppy was still drivable and very well
mannered.. No worries about
traction or shifting..
Hmmm.... She was downright
“streetable”..
Thinking
about the problem as I motored home like a law abiding citizen I theorized that
there was some defect associated with the detent pressure in the transmission.
After
getting home I checked the fluid just for laughs. It was fine.
Then I
pulled the air cleaner and disconnected the detent cable. It seemed very easy to move. Like it was not connected somewhere. Or broken..
I had it
adjusted pretty tight, maybe a little too tight. In my excitement during the last few days I have a feeling
that I may have overstressed some component of the detent system with my heavy
foot..
And the
rain is starting back up so I am restricted to indoor work..
Bah!

After
the miserable cold rain part of the cold front passed the weather cleared up
with little showers once in a great while. T&t7-1.jpg and t&t7-2.jpg gives you some idea. Sunny but about 15 degrees colder than
normal..
In t&t7-1.jpg you can see the little Airstream trailer
lurking behind the new construction. I have been living in it for 22 years and maybe next
year can get out..
Rustpuppy
is being jacked up for todays work in t&t7-2.jpg and t&t7-3.jpg with
bumper jacks fore and aft.
T&t7-4.jpg shows the completed work area. Note the large jackstands under the front and rear
subframes. On the other side both
wheels are chocked fore and aft.
Not taking any chances on getting squashed..
T&t7-5.jpg
is the underneath shot of the work area.
I
theorized (probably full of bologna that a stuck modulator valve might cause
the strange 3rd gear only symptoms. It was worth a shot as it is easy and convenient to check.
After
studying more in my Turbo-Hydramatic 350 Handbook (Ron Sessions) last night the
theory was looking more and more like wishful thinking..
It
was. The modulator valve is
working just fine, like the governer..
Damn.
During
today’s road test (made first thing) I noticed some more symptoms. The engagement of the clutches when
going into gear seem way softer than normal in both drive and reverse. I even tried a mini neutral drop from
1500rpm in drive and there was no bone shaking thump like usual.
It looks
like the line pressure is way low.
I have been wracking my brains about what would affect both the 1-2
shift valve and the 2-3 shift valve.
The governor pressure is a common factor and if it was stuck way too
high it would inhibit the shift valves.
But the governor is fine.
The modulator acts to oppose the governor pressure so I though that if
it was stuck low that was the problem.
This would cause the line pressure to be lower than normal too. But it is working fine.. Now what.. Mebbe there is an internal leak
in the modulator circuit?
Hmmm.. The detent
valve directs modulator pressure to the shift valves.. Could something be screwed up there? The deeper you look the more
complicated it gets..
It
really looks like the next step is to pull the pan and check everything with
transmission fluid dripping in my eyes.. Oh well..
At least I am having fun..

Cold
(never got up to 50) with a couple short showers but I was back out laying on
the cold ground trying to get ol’ Rustpuppy going again.
I took a
couple pictures, yesterday in the bright sun, of the location here. T&t8-1.jpg is from the middle of
the yard looking down on my neighbors house and the Pacific.
T&t8-2.jpg
is from the attic window on the new home I am in the process of building. (very slowly)
The
tallest rock (sticking above the Pacific horizon) is actually an extinct
volcano about 360 feet tall. I am
at about 300 feet above the sea and 1100 feet back from it.
Rustpuppy
looks small from up there..
Back to
business, this is a view of the action area.. It is pull the pan time.. (t&t8-3.jpg)
Like
magic the pan is off and the valve body out for inspection. (t&t8-4.jpg and
t&t8-5.jpg)
Unfortunately it checked out perfect. No flaws or defects anywhere. This is bad.
It gets worse.
There
are little shiny silver hunks and other stuff in the bottom of the pan and
mostly on the top of the filter.
(t&t8-7.jpg)
It get
even worse.
In the
pan I harvested this mess of rubber chunks. This is really not good. (t&t8-8.jpg)
And this
is a closeup of the filter again..
I don’t know what some of that stuff is but it don’t look good to
me.. The metal bits are like
sand.. Some dark and some
silver..(ror8-9.jpg)
This
transmission looks like toast to me.. Bummer..
To close
with a positive note. I figured
out an easy way to put the hairpin pivot for the detent cable lever back
in. Pry it open and prop it with
an external ¼” star washer. Then
insert it and tap it with a screwdriver handle to free the washer.. Worked slick.(t&t8-6.jpg)
It looks
like the rebuilt transmission I bought because I knew I was going to toast the
old one in Rustpuppy is going to go in..

The day
came for getting rid of the Prothane polyurethane bushings in Rustpuppy’s rear
suspension. First carefully
putting Rustpuppy’s passenger side up on jackstands t&t9-3.jpg and
t&t9-4.jpg) after pulling the bracket and prying down the spring the
bushings were out in a jiffy.
(t&t9-1.jpg)
Getting
the metal and rubber stock bushing in was not such a simple matter.. I started out being careful but ended
up pounding like a madman with my 3 ½ lb hammer.. I seem to have mashed up the end of the metal insert
so the bolt will not fit..
(Primitive Pete at work) I
had to get out my ½” drill and a ½” bit to clear out the mushroomed end..
The bracket and bolts were back in a jiffy and it was time
to proceed to the drivers side. I
figured out a more sophisticated way of prying the spring down on this
side (2x3 on the other).. You can see the markings on the flat
sides of the bushings where they were squeaking and popping..
When
pounding in the stock bushings it helps a lot to pry the eye of the spring open
by pounding in a screwdriver..
(t&t9-6.jpg Primitive Pete again)
This
side I took my time and hit at a 30 degree angle so the edges of the steel
bushing took the punishment and the center tube was untouched.. (t&t9-7.jpg see! I can learn!)
I was
careful to center the bushings in the spring.. (t&9-8.jpg)
For some
reason one of the bolts on this side was a bitch to get in. It took some weird prying and pushing
and I wasted about 40 minutes on what should have been a 2 minute job.. T&t9-9.jpg shows the finished job
on this side..
After pounding
in the front bushings and securing the brackets (leaving the big bolts loose
till Rustpuppy was back on all four wheels I laid under the rear bumper and
replaced the bottom urethane bushings (top ones were already rubber) with
rubber..
Funny
thing happened at this time..
Since I had my special pot-o-chili for dinner last night I was a bit
bloated.. I cut a huge fart
and felt instant relief. Then
about 2 minutes later I saw something moving in the sky out of the corner of my
eye.
There
were a couple of vultures circling the yard.. They must have thought I was dead and starting to
stink.. How humilating..
After
all the bolts were tight and everything buttoned up I took Rustpuppy for a test
drive.. Ahhh! What a difference.. The squeaking and creaking and popping were gone and the loudest noise
was the sweet sound of Goody through the Super Turbos..
And I
got Rustpuppy up to the axle whining speed and found that the level of whine
was only about 1/10 of what it was with the hard bushings.. Success!

It was

get it prettied up for installation.
I knew last year that the old transmission in Rustpuppy was not going to
last..
T&t10-1.jpg
shows the drab primer the tranny came with all the way from South Dakota.
I
decided to go with the Oldsmobile blue engine paint for the tranny instead of
the Star Trek silver I used on the last one.. T&t10-2.jpg
and t&t10-3.jpg shows how I propped it up during the painting.
T&t10-4.jpg shows the finished product.. Looking good..
I put Wade’s name and e-mail addy (t&t10-5.jpg) on the transmission as he gets the credit (good or bad) for this tranny.
Wade assures me that he has put some really special
building tricks and race oriented goodies in this transmission.
While I
had the chance I threw the tranny up on the scale.. (yeah right..
threw... t&t10-6,jpg.)
It was interesting to see that the standard TH350 weighs 121 lbs..
Unfortunately that is too much for an ol’ cripple like me

Faced
with the problem of getting Rustpuppy to town by myself I decided against
driving her with the crippled transmission and bumming a ride home and got out
the old towing rig I set up many years ago to transport Rustpuppy.. (back in 1995 or so)
T&t12-1.jpg,
t&t12-2.jpg, and t&t12-3 show the rig.. The super Disco bumper is plenty strong with that
steel girder inside. So I
just bolt brackets that support a towbar to the bottom of it directly.
T&t12-4.jpg
shows the hookup to the Suburban.
It takes a bit of getting in an out of the car to get everything lined
up but I am getting good at this..
Finally
on the road you can see the Nova is following the Suburban very
closely..(t&t12-5.jpg)
Actually
they are parked cause I am in the middle of the yard taking the picture..
I stay
on the old farm road as far as I can (about half of the 15 miles to town) and
keep the speed down to 40 on the highway but the trip to town was uneventful..
Now

You will
notice that there is no Test&Tune 13.
Ol’ number 13 would have been about the rotten time I had with the
driveshaft transplantation and organ rejection. I went through hell getting Rustpuppy’s old too short driveshaft
apart so I could transplant the slip yoke to the proper length but beat up and
mebbe bent driveshaft I got gouged 75 bux for locally.. The slip yoke on it was rusted into
uselessness..
Then my
mechanic Brett went through even more hell the next morning trying to assemble
the driveshaft. There was
something wrong with the slip yoke and after it got beat up and heated and beat
up some more the driveshaft is vibrating like Aren’s Nova..
Enough
about the crappy driveshaft. It
will be fixed next week..
Rustpuppy
was ready to come home yesterday but the weather was so crappy I put it
off. Raining and 60mph winds..
Today
was a much better partly sunny job and the story starts at Central Curry Truck
And Auto.. Bretts shop.. Here is a quote from Brett.. “If there were no Fords I would be out
of business.” Most of his work
(and he hates it) is on the little Ford trucklets. Rangers, Explorers. Broncos, and that kinda stuff. He even offered me some free late
model Ford motors that litter the floor in there..
T&t14-1.jpg
shows Rustpuppy lurking in the corner of the biggest auto repair shop I have
ever seen. (It used to be a fishing boat manufacturing plant.. Big..)
T&t14-2.jpg,
t&t14-3.jpg, t&t14-4.jpg shows Rustpuppy being moved around and hooked
up with the Highway 101 Historic Rogue River Bridge in the background..
T&t14-5
shows a corner of Brett’s shop showing how close it is to the bank of the
river..
There is room to fly radio controlled airplanes inside his
shop.. I am trying to talk him
into opening up a small body shop in the corner.. (selfish reasons..)
It seems
like trailing a car is more stressful than I remember. Partly because of the radial tires on
the Suburban making the rear end move in strange and uncomfortable ways from
the pressures on the towbar from Rustpuppy. I left the motor idling in Rustpuppy for the trip home and
t&t14-6.jpg shows the whole herd together on the yard..
I ran a
series of test drives to verify all of the functions of the new tranny and
everything checked out great (with one quibble and one problem). The governor, modulator shift linkage,
etc all checked out A-OK..
The
problem you already know about..
The driveshaft vibrates like a booger at about 50 mph and then again at
100..
The
quibble is the difference in the 1-2 shift.. The old crapped out tranny had an instant shift while
the Wade special has a softer, longer shift. Positive but just longer and softer.. More on this later..
I
decided that since I had “The Hole” still uncovered from the transmission
troubleshooting last week that I would get in there and check the tooth count
on the speedometer drive gear.. T&t14-7.jpg, and t&t14-8.jpg..
19 teeth on that critter.. Bummer.. I
think the maximum is 22 teeth and that is not enough to correct for my big
error in the speedo..
60mph actual = 74 mph indicated..
I
planned on finishing this part of the story with the pretty picture
through
the hole at the nice blue tranny..

But
later this evening while I was washing dishes a sudden urge came over me.. I was still fired up from the transmission test runs and I
had the idea of making a G-Tech run to see what was up.. So I left the dishes in the sink
half way through and jumped into Rustpuppy for a quick trip down to the south
end of Rustpuppy run. Something
must have been dragging and grinding in the old tranny because during the test
runs there seemed to be more beans than before..
I got to
the south end of Rustpuppy run.
Weather good, wind still, no traffic, Got staged ok. The launch seemed to hit harder than usual so there
was much more wheelspin than expected. Enought to jog Rustpuppy’s rear about 3 feet to the
left but I stayed on it. (I bet I lost a lot of time there)
Finally
hooked up and went good.. I
hit the shift lever with the shiftlight at 5800 but the slight delay of the
softer 1-2 shift had the rpm up to about 6200 before pulling it back down with
a vengeance. Instead of chirping
the tires it felt like Rustpuppy was twisting..
Time for
third came in jiffy and I stayed on it past the end of the quarter because the
sun was on the G-Tech again and I could not see the LED’s..
As I
coasted down for the turn off I could see the flashing leds but couldn’t read
them.. Around the corner and
off the highway and I could see 13.73@106.5
(corrects to 103.5)
(t&t14-10,jpg and t&t14-11.jpg) So almost the exact same e.t. as
with a perfect launch and picked up almost 1 mph.. Something must have been dragging in the old tranny.. Headed home to my dishwater..
I am
sure that with a good launch
Rustpuppy will be well below 13.5.
And then it is time to start tuning the timing and mixture for some
horsepower.. Yowza! I am amost sure Goody is still at 28
degrees total advance..
More to
come..
