Thanks for all the great info!

A couple final questions... Is 750 cfm large enough for a 440 stroker which gets mostly mild mannered street use with the occasional WOT?

If I opt for a Proform 750 with vacuum secondaries, they offer two choices... the street or race series. Would there be some benefit to getting the race series which offers the following features, or would they be unnecessary for my needs and just cause me headaches?

* High-performance Race-Series, hand assembled in the U.S.
* Utilizes the Proform carburetor high-flow main body
* Adjustable, screw-in air bleeds and high-performance down-leg boosters
* Maximum air flow: no air horn, choke tower, or choke control
* Centered on Proform billet throttle base plate
* Adjustable secondary air flow cam bracket and welded throttle shaft
* Button torx head throttle plate screws
* Power valve blow out protection and slip link mechanical secondary linkage
* Assembled with Proform billet metering blocks
* Changeable idle feed restriction
