Hmm, the cfm difference in six vs. V-8 is new info for me. Can you guys explain it further? I know that 2-bbl vs 4-bbl are calculated differently for cfm, but I don't understand why the number of cylinders a carb is attached to should make a difference. MIght help explain why the 292 feels a bit underpowered with the 4-G compared to the 2-GC that was on it before (though I pulled that 2-CG directly off a junked 305 V-8 (similar CID to the 292)), so now I'm even more confused!
