I recently purchased a 67 F-100 with a 352 and 3 on the tree. I'm gonna stoke it up a little with a set of headers, performer intake, comp cams thumper cam. What carb would be best? 600? or 750? I'm having the heads reworked, ported and polished also. The engine has 43000 original miles on it, the truck is barn kept, one owner, doesn't smoke, runs like a top.

A 600 CFM would be plenty.

Formula for choosing a carb:

RPM x CID/3456 x VE. (VE = volumetric efficiency)

(had to look it up, couldn't remember it to save my butt!)

We generally figured about 87-90% for VE.
