700 cfm holly

[66 Barracuda]

So I read everyone discussing eddys and hollys. I have decided on the Holly. So which one. Most people seem to discuss the 650 and 750. What about going in-between? "700" I am building a mostly street driven car but would do some track time ocassionally. All articals I've read have left me leaning toward 650 mechanical secondaries. Help?

Lunati cams says 700 cfm. but I am lacking the headers in there setup and am running a single plane intake vs dual . A have managed to successfully install 340 hi po manifolds. Didn't want to deal with headers.
Am I right thinking 650?
Maybe even 750?

The way I see it, being a street driven ride that isn't turning a lot of RPM, I'd run with either the 650 or 700 cfm double pumpers. I think you'll be fine and really enjoy the snappy throttle response.

thank you Rumblefish. I think I'll go with the 700.
