So I'm putting a 350 in my 1984 T/A. I'm curious what others who have done the same have done for a carb, as I'm currently deciding. I'd like something that's the best cash to performance ratio.

 

The better question is what kind of 350? A 150hp 70s smogger, something more modern? Any aftermarket parts?

 

Block out of a 70's box truck. 190cc heads out of my race car, cam out of my race car, edelbrock aluminum intake.

 

Going to need a hell of a lot more info than that. Full build sheet, or making recommendations is a guessing game.

 

if you like constant fiddling ,then buy a holley carb. HOWEVER if you like a "set it and forget it" carb. the only choice is a edelbrock carb

 

Stay away from edeljunk, mine has not been set it and forget it kinda carb, it likes to remind me its still there, could be mine just has a gremlin in it.

 

A 1970's truck engine is probably going to have very low compression (assuming it is stock). I would be real worried about sticking a "race cam" in anything with low compression. What are the cam specs, the cylinder head combustion chamber size and the type of piston in the shortblock?

 

edelbrock vs holly will go on forever. anything you get will need to be messed with to work properly. before i knew anything about either i was looking at what everybody at the track had and most of the guys that were running good had some version of a double pumper so thats what i got. i got a 4150 750 and it will run a 350 out of the box but anything you get will need tuned to perform properly, i got a book and figured it out

 

Yeah, the motors not stock. Essentially we're taking the block because it's four bolt, and using most of the stuff off of the race motor we have sitting around. We don't want to bolt a straight up race motor in, because my dad's worried about the fact that the valves and pistons aren't really suited for street driving. I'm not sure on the cam specs, etc.

I'm leaning 650 double pumper as well.

 

A 650 dp holley is great carb for a mild performance build. Don't want to get in a debate about carb brands but in my experience a Holley is a much better performance carb then an Edelbrook. I started with a 650 dp and then stepped up to a Proform 750 main body and been really happy with it. Good luck.

 

That's been my experience as well in the past as well. I do have to say that on a local car club member's 68 Camaro he bought an Edelbrock for a mild 327 engine and all he does is go to car shows and cruises. Out of the box it was easier to get it dialed in than what I have had to do on a Holley.

 

Edlebrock's are good on stock or slightly upgraded engines. Your combo needs a Holley and some tune time. 650 cfm is probably to much. The rpm the stock rotating assembly will handle in a 70's block is probably 5500 rpm occasionally if everything is in like new condition. Even though its 4-bolt the crank and rods are same as 2-bolt. Here is a formula on how to get the right CFM for your engine.

Engine size (CID) x maximum RPM / 3456 = CFM

350x5500?=1925000/3456=557 cfm
