    I have a '59 364, so it has the 1.6 ratio rockers and the later heads. It also has a TA 112 cam. I am going to do Doc's mod to the stock 4bbl intake manifold. Will also have dual 2.25" exhaust. Wondering if a Edelbrock 750cfm would be a good fit? Russ thought so, but I figured I'd get more opinions before I buy one.

    I think this might be a good application for one of those new AVS2 models with the annular boosters. A 650 would probably be a nice choice for a 364, but asking for a carburetor opinion is going to elicit a lot of answers!

    I ran a 750cfm Edelbrock on my 401 until I put a factoy dual quad setup on (1250cfm), ran good both setups, actually better with duals. And that with a stock or really mild cam.

    Think factory afb's are supposed to be rated at 625cfm.

    I would think you should be fine, though have read you may have to dial in the jets and metering rods sizes.

    I second the AVS model choice. The AVS has an adjustable air valve like a Q-jet. The allows the carburetor to deliver only the air flow the engine demands. It sizes the carburetor to the engine demand. The AFB has a counter weighted air valve, you can't adjust that.

    Thanks for the responses. I keep hearing that these motors are CFM hungry, but I was stuck between whether I should get a 650 or 750. The AVS2 carbs look really cool! I'm going to be dialing in the car with a wideband once it is running.

    the factory carb on the 401 was actual 575 cfm. i ran 650 and 750 0n a 344 ci. the 650 had a little better throttle responds but after 4000 rpms the 750 will start pulling better.

    That size motor with a duel plane Intake will run fine with the slightly too large 750 Carb!

    Hmmm. almost think the 650 will be a better choice considering this thing will have a dynaflow behind it.

    I would get the AVS carb before the Edelbrock they look like nice carbs. There a 750 won't hurt ya. I would do the 750.
