327 carb.

I've been attempting to put together my 327. It's currently stock, but have collected some parts over the years and now it's time to put it all together. My concern is that the carb I have is too big for the motor. It's a Holley 750 dp. I have fuelie 2.02 heads, DZ aluminum intake, and forged flat top pistons. I havn't pick the cam yet, but thinking of going with either an extreme or thumper hydraulic comp cam. Any thoughts on the size of the carb? Should I look into selling the 750 and replacing it with a 650? Thanks for the input.

Not much info to go by, but generally speaking, a 327 on the street w/an AT and hydraulic cam is not going to need a 750 DP. I'd use an XE if the choices are it, or a thumpr.

A 600-650 cfm carb will be better suited in most cases, unless you run a Q-jet, which should perform good w/this engine but not w/a square bore intake. I'd stick w/a 'vacuum' secondary carb like the Holley 1850 or an Edelbrock 600 Performer, that sort of carb unless the cam is radical, stick shift, or loose TC and low rear gears and light weight vehicle, w/e driven, etc.

I like the Performer air gap #2601. Idle to 5500 rpm, non EGR that will accept either the spread bore or square bore carb's. With it's design, you would have more choices as to what carb. you can run either the 600-650 Holley, edelbrock, or the Q-jet. Personally, I like the old 650 spread bore Holley but, the Q-jet would be more compatible with stock linkage for throttle and transmission controls and would be easier to install and cheaper without having to buy a bunch of bracket accessories. JMO.
