Best Holley carb for 347 stroker combo?

[NicksBullitt]

My dad is putting together a 347 stroker, pretty hot package, but does not know which carb to go with. He was thinking a 700, but I did not think that it would be enough . We have looked and really haven't seen anywhere that really outlines HERE IS WHAT YOU NEED. So looking for suggestions......

347 stroker Forged Rotating assembly
Lunati Voodoo 61004 cam ~540 lift 280 duration.
Aluminum heads Pro Comp 190cc
roller rockers TRW 1.6 Stainless
Edelbrock Dual Plane High Rise
4sp toploader
9" 3.73

Any guidance is appreciated!

use this formula:
Engine size (cid) x max. rpm/3456 =cfm

cfm x engine efficiency(note-race car engines are 90-95% efficient)

If you don't mind me asking, where did that formula come from?

My math comes up with ~700. I would have thought he needed a 750, but I really don't know. Thats why I asked.

what do you mean??

the engine is just an air pump. always was and always will be.

the formula is how much air can be pumped thru the engine in one minute.

I mean, that I edited the post to include cam, intake, transmission, differential, and head specifications to the original post. I thought these details might help the discussion.
