Why not?
In the process of roadizing the monster OLDS again. Engine
being restarted, (electrical fire caused by heavy handed,
'read clumsy' son), after wiring sorted out and starter
reinstalled. Transmission is history and needs either
rebuild or replace. Body work is complete and needs paint.
Looking for CHEAP, NON-RUSTED, back bumper for 1979 OLDS
Cutlass Supreme. Inspection weenies will NOT pass the one
that is on there even though it makes current bumpers look
like plastic straws...
For interested parties:
1979 OLDS Cutlass Supreme - 1973 OLDS 350 Rocket with big
cam, bored .060" over, high capacity oil pump, rebored
crank journals, aluminum manifold with 750cfm Holley
double-pumper, headers, updated ignition, oversized
radiator, complete rebuild 10K ago. Just broken in now
and ready for summer cruising. Car had originally a
305 Chevy engine which passed away. Still have original
rear end that is being babied as long a possible. Car
has 144,500 miles on some parts and about 15K on all of
the important stuff, (front end, brakes, etc....)
Any OLDs lovers out there???

40.2 | W-30 HEADS ID? | SWAM2::KLINE_ST | | Mon May 06 1991 16:49 | 5 |
| does anyone know how to identify the w-30 heads on the 1970-72 455
engines? also, is there a way to verify matching engine numbers for
these years? (like where is the engine serial number pad?)

Anyone know if Summit Racing supplies parts for an Olds
403CID engine ? They list practically everything else.
This is the stock motor in my 1979 Pontiac Trans Am.

40.4 | Olds trouble help needed.... | DNEAST::WHITE_BRYAN | Stupid people shouldn't breed.. | Tue Jun 11 1991 12:26 | 18 |

Question:
Request for long-distance trouble shooting/hints.
Problem:
After 3-4 miles, (@45 or so), of driving engine
shuts down. Will restart immediately unless I
accidently flood it. Will idle indefinately...
I have had the carb redone, (Holley), the timing
etc.. checked. I have run out of cheap things
to try. I heard that it could be a part of the
distributor that breaks down on GM products?
Any helpful hints would be greatly appreciated....

| fuel pressure? fuel pump going bad?

40.6 | Fuel pressure? | DNEAST::WHITE_BRYAN | Stupid people shouldn't breed.. | Wed Jun 12 1991 10:19 | 6 |

How can us amateurs check something like fuel pressure? The
pump was new when the engine was rebuilt 10K ago and I have
been assuming it is ok....

40.8 | Vacuum/pressure gauge | TUNER::BEAUDET | | Wed Jun 12 1991 12:47 | 7 |
| Some vacuum gauges can also check pressure...in particular fuel pump
pressure.
If you have one check the directions...if you don't they are not that
expensive and are really handy for tune-ups etc.

40.9 | Filter new, lines "ok".... | DNEAST::WHITE_BRYAN | Stupid people shouldn't breed.. | Wed Jun 12 1991 14:46 | 11 |
|
Quick check revealed dirty fuel filter which was replaced.
Fuel lines seem to be ok and when unhooked and engine
turned very briefly gas pumps out. Like I said before
the engine will idle fine just won't take any rpm's at
all...
Is there any electrical problem which will cause the same
type of symptoms?

40.10 | Just a shot in the dark | CRISTA::ROCHE | | Wed Jun 12 1991 14:56 | 5 |
| Does you gas tank have a vented cap or vents lines? If either is
clogged the fuel pump could draw fine at idle, but as demand
increases the pump may not be able to draw as well due to no air
being able to enter the tank. Try driving with the cap loose at
the speeds you've been having the problem at.

40.11 | Are you sure the Carb is okay? | DUSTER::LIND | It keeps getting better and better.. | Thu Jun 13 1991 08:54 | 9 |
| Are you sure the Carb is set up properly? Are the jets right float
right etc.?
It sounds to me as if there is a carb problem if the fuelk is getting
there okay.
You might also want to check out the coil.

40.12 | What about plug reading? | VCSESU::D_SMITH | | Thu Jun 13 1991 12:31 | 9 |
| If float levels are correct at idle, and the pump is not delivering
to spec, you should get RPM's out of it for a brief, then she'll
drop off once the float bowls empty.
A bad coil would prevent hi RPM revs. and would appear to be gas
starved. How do the plugs look? Black would be ignition, white could be
lean carb condition.

Well, turns out the problem was in the fuel system after all.
Replacement of every thing back to the fuel tank did NOTHING!
Finally a minor application of compressed air into the fuel
line solved it, (for now anyway). My personal opinion is that
anything blocking the line is still in the tank and will come
back to haunt me anyway.
Otherwise we replace the double pumper with a 500cfm vacuum
advance 4bbl. Much better response anyway as I think the
other carb was just too big. NOW the #1 son announces that
he wants to sell his half to either me or anyone else and
is leaving to seek his fortune in the sin_infested_streets_
of_BOSTON!.... I offered him $1K for his half and believe
that I have him over a barrel with no room to negotiate...
"My plans" if the deal is accepted are to remove the TH400
for a complete rebuild, (it's tired and shifts "funny"),
and a shift kit, location and installation of another
rear end, (current one is toooo tall) and finally cover
up the primer that has been its color for the past couple
of years...
Then.....we shall see....too bad its so far down to NH for
some "legal" racing...

40.16 | Try TCI tranny instead of rebuild | GIAMEM::IRWIN | | Mon Jul 15 1991 11:31 | 7 |
| Bryan,
If you plan on rebuilding, you should look into a new TCI tranny.
Cost is about the same , and I beleive they have Street/Strip versions.

40.17 | 1968 W-31 cam/lifters, will they fit??? | GIAMEM::IRWIN | | Mon Jul 15 1991 11:35 | 17 |

I have some questions of my own.
My Brother-in-law and I just bought a 1965 Olds Cutlass Holiday,
which will end up being a 442 lookalike.
Well it has a 1967 425cu out of a Delta 88. I was wondering if a
W-31 cam/lifters for a 1968 455cu would fit. Some precheck with
some other motor heads and chiltons, I beleive it is a 39 degree bank.
any help???
Thanks,
Art

40.18 | TCI? | DNEAST::WHITE_BRYAN | Stupid people shouldn't breed.. | Mon Jul 15 1991 14:18 | 9 |
| re. .16
Say some more. I am not familiar with a "TCI TRANNY". I
have a rebuild price of <$550 quoted from two different
transmission rebuilders. I did not try to get a quote on
a new one as I thought we would be in four digits to get
a new one...

40.19 | TCI tranny | GIAMEM::IRWIN | | Thu Sep 12 1991 07:03 | 14 |

Bryan,
sorry it took so long to respond, been having troubles with the
system. I don't know if this is too late but the TCI tranny for example
a 400 turbo is going to run be $600. It will cost less obviously for
the 350 th. Just call a competition shop and ask if they can get and
tell them what you want.
Its pretty much a regular tranny w/ shift kit.
Hope I wasn't to late.

| RE:17
I'm new to Notes so this may be too late but the OLD's
cam profile will fit in any olds block. You may have to watch
for the lifter set though. I'm not positive if the lifter
set from a 455 will fit in a 425. If you do use the set though
they MUST be placed back in the same position as before (ie intake
lifter cyl.1 to match that loeb on the cam etc.)if it was a used
cam/lifter set as it has now seated for that position. There is an
outlet called Mondello Performance who custom grinds cams/parts
for OLDSMOBILES ONLY. I have used one of his cams and they are far
superior to anything avail on the market. If your interested I can
send you a copy of the catalogue or the actual W-31 original cam
profile. If you go with that cam I would aleast get a new set of
lifters (Speed-pro for example.). Keep in mind the W-31 is old
tech. thinking. The new Modello cams have LOTS of lift and less
timing to work very well at higher rpm's yet less timing gives
better bottom-end. Not that a bigblock Olds needs more!

| Sounds like you blew the fuel line backwards to the tank. In this
case, the inlet strainer was backflushed. The dirt in the tank will in
time, clog the strainer again. The strainer is a slip fit on the end
of the pick up tube. I had no trouble with Olds and Buick parts guys
but the Chevy parts manager tried to tell me I had to buy the whole
unit, guage and strainer both. I said, "but, but" and he put me down.
So I got another strainer from Olds and it fit on the Chevy with no
problem. I had 3 cars konk out as you described, in one year. I had
drained a full tank on a car I was going to junk and put the fuel in
each of the three cars. What had happened was during the siphoning
action fuel ran down the undercoating of the tank and I foolishly
"saved" it by placing a bucket under the tank and caught the spill.
Well, examination of the strainer showed it was almost a solid black.
The tar based undercoating apparently did not 100% dissolve like sugar
in hot water and got caught up on the fine mesh of the strainer.
Naturally, not wanting to drop the tank to replace the strainer I tried
all the fixes everyone has suggested but the real fix was the strainer
in the tank
