65 , is it a stock 350 ?if not what rpm range do you expect to run with it ?

We recently bought it and from what the previous owner told me it's mostly stock but has an RV cam in it? I assume that's a slightly torque-ier cam but not 100% sure.
I think I mentioned before that I am looking for medium performance and highly reliable......so not super high RPM's

if its mostly stock Ill say its safe to say youll never rev it past 5500 RPMs. If thats the case 600 CFM is plenty.
Or like a couple of others have said, a Qjet would be wonderful, Qjets are hard to beat if tuned properly, hard part is finding someone who knows how to work em. Q jets are basically 800 CFM, but cause of there spread bore design, they act like a small carb at part thorratle, wich helps it be more responsive.

makes sense, thanks for the info. Learning more every day!
I believe it's a q-jet on there now....a rebuilt rochester I think the previous owner said. What are your thoughts on those? I have heard they aren't the greatest.

Like I said, when propely tuned there hard to beat. Alot of people dont like em cause they are a bit complicated, & when they screw up, they really take a crap. The Edelbrock Qjet IS a Rochester Qjet,They got the rights to it a few years back. Its personal preferance. Im no good with Tuning a Qjet,but I had one done by val hedworth (famed stock eliminator racer) for my 402 in my Camaro after playing with differant carter, Edelbrock, & Holleys, & the Qjet outperformed & out MPGed all of em.

now all I have to do is either learn how to tune it, or find someone really good at tuning them.

Chances are the stock carb you have has a automatic choke, but not an electical one. It is probably the old thermo spring type, that relases the choke after the engine warms. It was a step up over the manual, in terms of automtive advancements, but didn't come without their problems.

Streets, that carb looks like it has the remains of a fire extinguisher on it. Or was that sitting beside the drum set in the sub basement with the dragons.

Messed up my non-adjustable Johnson rods too that way... Hehehehe

Ouch, I hope it didn't leave a mark! You must remember to remove the Johnson rods immediately after use. Particularly the non-adjustable ones.

It does have the thermo spring type automatic choke.
I found a guy that will put the car on a scope for free and help figure out what's going on with it. Hopefully that will shed some light on the problem.
