This two carbutors has the emission provision. eventhougth the vehicle doesn't have to pass emission inspection, I am environmental conscious, and want carburetor that will give the right mixture for complete combustion. On the same token, I want maximum horsepower. Which of the two carburetor will you recommend?

I'm a q-jet man, so that would be my first recommendation. However, the new Edelbrock q-jet you mentioned will cost right at twice what the Performer will cost. So, you'll have to decide. Either would give good performance and run cleanly when properly tuned.

With either one, you'll be eliminating the computer control, so you will have to go with a vacuum/mechanical advance distributor. Your stock unit will not work properly without the computer.

I like the q-jets but they can be finicky
as for Edelbrock runs good out of the box
good street strip carb but if gas milage is
not a concern Holly 650 double pumper,change
the jets to 71 primary 75 secondary.

The ODB

Definately Edlebrock 600,
and go with an MSD vacuum advance distributor.

I'd have to say a Holly 4160 or was it the 4150?

Anyhow I'd go with a holly 750 vacuum secondaries not a double pumper and modifiy it as much as you can to get more air in it. The double pumpers aren't as fuel effecient. I think there was an article on motortecmag.com that said how to get more air into em. Performance carbs can be 1000 CFM. cfm is just the measure of air introduced you can always mess with the jets on any carb. Also just for your info q-jets can be modified to about 1000cfm, don't ask me how though. Why do you think the performance carbs like dominators are 1000cfm cause for a 400HP engine it doesn't sacrifice top end HP or bottom end torque/HP. But why don't you just port a 350TPI manifold and have a custom chip burnt or learn to burn em? Carbs just don't stay tuned like TPI or TBI. Unless you really know your stuff when it comes to carbs I'd say stay away or start reading. Also if you do go with a carb I'd say get an O2 sensor and gauge so you know when it's tuned and your not reading spark plugs and playin the guessing game, but you have to use sensor safe gasket sealent.

Fast-Formula

A 750cfm Holly is way to big a carb. for his combo. He's only useing a Edelbrock Performer
not a Per.RPM,If HOLLY is the way he's going to go 600cfm is plenty big enough.

The ODB

Man! you guys are hurting my feelings here. I was convinced that I had sparkplug reading down to a science.

Anyway I say the 750 cfms is not too big for a 350, 327, or 305. I just have a grudge against Holley carbs.
As much as Holley has rode the wave of racing performance, I feel they have also given carburetors a bad name, because they are a bit too complicated to fine tune for the average street enthusiast. So I don't like Holleys.
But for the record, you should have great luck by staying in the 600 cfm range no matter which brand you go with.
good luck again,

Mr. TA

I didnt know that! I thought I could just throw in an edelbrock performer carb and have no problems, I didn't know I had to replace the distributor. So if I have to replace the dist. will that mean the computer is no more? or how does that work?....Also what will happen if I dont replace the dist.? Thanks for any comments or suggestions

The ODB

If you go to non-CC carb then you should go to non-CC distributor. If you fool a couple of sensors then the CC-distributor would work enough to drive the car... but definately not the way to go for performance.
A non-CC distributor will give you total control of the timing.
If you trash the computer, just have a tranny shop install a pressure switch to ensure TC-lockup.

Mr TA: Looks like you and I are in the same boat. Getting a Holley 80457, and a vacuum controlled distributor. At work the other day i did some research and found this: All police cars from 1983-1993 that had carbs also had vacuum controlled distributors. And that 305 distributors are interchangeable with 350's. Any auto parts store will have one of these distributors in stock, thus avoiding a high price for a new performance one from Jeg's or Summit.

I feel I am fairly clueless on this swap. When all the parts get here by Friday, looks like i'll be having some fun, if you can call it that. Hopefully [with how slow i am] it will be back up Wedsneday.
