After all, the primary side of the 750 is just a modestly sized 2bbl .................. equaling about
(750/2) X .67=251 when rated as a 2bbl.

LOVE IT! Bingo! And then at the same time, I still use a 600. I always gained mileage on the direct 2bbl. to 4bbl. swap. Even with a modest cam installed afterwards, it still a good size.

Yes it is and it probably won't see much over 4,500 rpm's for the most part. I thought about a 650 eddy and a performer intake or would the rpm performer intake be a better option? This car will not see any track time, probably some stop light to stop light fun once in awhile. My goal is for the car to have good throttle response and decent low to midrange torque. I want the car to be able to get out of it's own way and be able to pass other cars with out difficulty

I think I stated this before in one of your multiple threads going on but here it is again anyway, even if I didn’t.

On my 5.9, I am using a 600 AFB, RPM intake (AG only for a Magnum engine) Hooker Super Comp headers @ 1-3/4 into a 2-1/2 exhaust. Works just fine. The stock cam in that engine falls off @ 4500.

You said your looking at a Edelbrock 650, which means your looking at there AVS. Correct? Go for it. At the level your building this engine so far, I highly doubt you’ll see a difference between the Performer and the RPM.
