Did you get your carb yet? If so, how you liking it. This is what Pro Systems recommended to me.

 

It is sitting on my shelf waiting for its opportunity to prove itself. My intake should be back from porting in the next few days. So, the track testing will begin.

 

A 750 VS carb will be fine....they put 780's on 302 chevy's back in the day (high rpm motor)
For the street a VS carb is fine....trying to get every ounce of power... a DP carb is the best choice.

 

I do have to add that when I daily drove my '70 Camaro, I switched from a 780 VS carb to a 750 DP. The car was immediately more responsive and fun to drive. There weren't any drivability issues at all like people try to say there will be. I honestly don't see any reason for VS carbs to exist. This was with a mild SBC that ran high 12s. Now, going too big is a real thing. But it takes a significantly over-sized carb to really make it noticeable.

 

VS carb is fuel efficient and some fun

DP carb just straight up fun....until you watch the gas guage while tooling down the interstate at 65mph+

 

You can fix that with a wideband and some machine drills. All you have to do is drill out the PVCR and then jet down until the cruise is in the 14:1s and the WOT is in the 12-13:1s and viola. Same fuel efficiency as a VS if you can control your foot.

 

Holleys,, Infin adjustable. was racing em back in the 70's. Always replaced em with carters or Q-jets. Many carb builders and myself always thought holleys had too many band aids. Couldn't run em and forget em. Do the Q-jet. you'll be much happier and have gas money left to go buy a beer and watch someone tune they're holley ,,,again. (IMO)
