Adam,

All due respect, you are jumping the gun something awful. It sounds like you need to spend some time and a little money figuring out what you have before you go balls deep into a rebuild.

1.) If you don't know what you are doing rebuilding a Q-Jet you probably made a few mistakes. Even seasoned car guys trash Qjets because they can be hard to tune or work with. I'm not going to say run to a Holley, but this establishes that your carb is an issue.

2.) You had a big vacuum leak. If you tried to tune it with the open line you need to redo your tune.

3.) The vacuum advance that I am speaking of can help your car run cleaner. Make sure there is a vacuum line running to your distributor.


If you can, take a couple pics and post them up. And some more info about the underhood setup would help.

idk lol, where they attach to the block itself the metal and rust is coming off in rather large flakes, not to mention even with a new header back exhaust i still here exhaust coming from right infront of me so i know there's a hole in them somewhere, how much are a nice set of long tube headers? i want more acceleration in this puppy lol i dont care about top end speed really, just 0-60, i never go faster...unless on the parkway lol

$170 with the discount posted on here. These are also ceramic coated so they will look nice for a while and will keep the underhood temps down. That exhaust is probably an exhaust leak from blown gaskets or a monkey fisted install.

i didnt do the rebuild, my dad is a general foreman over at NJ transit, he had one of his machinists that used to be a car machinist rebuild it, he said he has rebuilt many cars and carbs lol so i trust him, he just said that the rebuild kit itself did help alot although alot of the internal workings looked pretty worn, and my friend's dad tuned the carb for me, the vacuum leak we found when we brought it home from NYC, those bennies just dont know how to take care of cars lol

WBT is right, time to stop guessing & start testing!

you might just be seeing flakes of old coating & hear gasket leaks. amazing what a sandblaster and some eastwood manifold paint will do to old rusty headers:

Yes, not as good, but this was with hand sanding and painting pitted headers.

ooo not bad, i want to get a new exhaust regardless of what happens with the engine, it just doesnt sound mean enough and it feels like it is being really held back, the carb i was thinking about going Edelbrock, what would you guys think? i like Holey, but i heard Edelbrock is just as good and i can get them for cheaper from my buddy. any who, when i get my first few checks i was going to go for long tube headers with an x pipe and duel exhaust. now back to the engine, i want to learn how to rebuild engines eventually, so sooner or later i want to get a crate and drop it in while working on the engine, or maybe have a beater while i rebuild that engine, not sure yet. oh and yes there is a vacuum line running to my carb lol

BonzoHansen 01-14-2010 08:13 PM

Vacuum line running to the can on the distributor.

An Edelbrock carb is fine. They are based off of the Carter AFB.

hmm im not sure if there is, i believe someone said that it wasnt a vacuum advance distributor, but i cannot remember, i will have to check when it is sunny 2marow, should i take pictures of the engine if i can get my camera working to better explain everything?
