Thank you John. I hear what you're saying about over carbureting an engine. If this were strictly a drag car, I might be open to slightly larger cfm carbs but realistically I'm down to 3 (possibly just 2) choices. It would be interesting to know if there is a difference between original Max Wedge Cross ram 750 AFB carbs (3705SA) vs more modern Carter Competition Series (4760) 750s? If it is a wash, I could eliminate one. I'm also considering a pair of new AVS2 650 carbs with annular boosters for the throttle response as suggested by Vortex_Jeff. Maybe I'll try a set of 750s and the AVS2s and see which pair the engine likes best. So now, it's a matter of getting the engine together for this Spring.
