Custom cam Vs. Futral F12/F13 How big of a difference would I see with a custom Comp Cams XFI/X-ER 230/230 .612/.592 111+2 LSA cam Vs. a Futral F12 - 230"/230" .595"/.595" 112+4LSA?
With that being said, is there that big of a difference to jump to a F13 230"/232" .595"/.585" 112LSA?
If my calculations are right the custom 230 has 8* overlap, F12 6* F13 7*
This is on a all bolt on stock headed '98 A4 with Vig 3200, 3.23, LS6 etc
Thanks a lot. Post similar setups, and how you like them. Thanks.

Close your eyes & take your pick, those specs are pretty close to each other to make any real difference.. If I had to guess, the custom xfi/xer cam might be just a tad better under the curve.. All three cam will probably peak in the 6200 rpm range.

I think the Futral cam will produce some better torque numbers and peak power. Allan has spent a lot of time testing those cams, and has not made many changes to either of them. If it was my choice I would go with the F13. I think on a stock headed car any cam with over .600 lift will probably hurt you a bit since most heads fall off after that.
