There are some vacuum advances that dont have vacuum applied to them until you get on the gas pedal. This is called ported vacuum. When you hit the pedal, the extra fuel fron the accelerator pump in...

Glad I could help. When you get a stumble or hesitation most folks go straight for the carb.
You can fix this without pulling the distributor. Pull the cap and rotor. You'll see where the vacuum...

I found an answer to my own question.
An outfit called The Parts Place has a complete manual trans conversion kit. It has pedal assembly cross shaft, rods, and all the clips, ***** bushings, etc....
Accelorator pump in the Qjet or maybe a bad vacuum advance in the distrubitor. Should be about the only two things that would cause that. Also check for late timing, that could also make it run hot....
I'm helping my son build a 69 skylark for a street machine. It was an automatic and has power brakes. We want to put in a 4speed. Since the brake and clutch pedal assembly is scarce as hens teeth, my...
This might be an old question, but what is difference in rocker arm ratio between cast and stamped rocker arms and what years were they used?
I should remember this, but just got a case of CRS...
Just a thought. If your car had a points ignition and was changed to an HEI, a commonly overlooked item is the supply (BAT) wire for the points ignition is a resistor wire.
This supplies 9 volts to...
Does anybody have the brand names and part numbers for neoprene front and rear main seals for a 455?:confused:
T.A. Performance has everything you need and a great tech staff to answer all your questions.:shifter:
A lot of prople dont keep th primary choke pull-off on the carb. This part acts as a "shock absorber" to slow the opening of the secondary air valve thus preventing the problem you described. Thus...
Not a problem at all. Just use an early style intake or any aftermarket intake. TA Performence and Offenhauser both make very good ones.
This might be out of left field. Do you have a vacuum advance working when cold. Could be not enough advance time to burn all that cold enrichment. Let us know what you find.:confused:
First, why get a rough uidle cam and smooth it out with roahds lifters? Seems like defeating the purpose pf the rough idle.
Second, one of the weak points of the big block Buick is the exhaust flow....
Sounds like a good solid plan. Doing everything right the first time is the way to go.
However as tothe edelbrock manifold, it never showed me very much promise. We had a 455 on the street for...
I would like to buy a set of headers to fit a 69 skylark with a 455.
We have this motor in a 1953 Henry J and this is the set that works.
We drag race this car so long tube headers are what we...
This isnt BLACK MAGIC.
Any engine builder who doesnt do the best he can do on any engine shouldnt be doing it at all. Find a shop who does a lot of competition work. They will fit your needs....
Gary Dyer makes a nice complete blower kit for not too bad of a price. Has everything you need to do it.
You will need a 455 flywheel and 455 motor mount brackets. Also a different fan shroud if I remember correctly. Also a 455 exhaust system.
Aside from any minor glitches, you should be good to go....
It worked on a 68 skylark we did.
TA Performance has just about everything you would want for your 455.
I would guess, however, you might have to modify your oil pan and make a new pickup.
The buick 455 is lightweight and coupled...
If you have a clutch fan it could be bad. Run it till it gets hot and watch the fan while somebody shuts it off. If it keeps spinning a bit after you shut it off, the clutch os bad. It will slip and...
It worked on our 1968 skylark.
My own favorite is the Offenhauser 360 manifold. I've had great sucess both on the street and the dragstrip. They also make a dual 4bbl version. Yoiu should find one at a fair price on EBAY.
A hint to anyone making mega horsepower and using a Turbo 400.
Back in the day when I worked for a chev dealer I found out that the big square potato chip vans with a 6.2 diesel had turbo 400s with...
