I am currently running a 331 intercooled F2 setup. I have been a best of 1.35 60ft with an ET of 8.88 @ 154. My suspension is new so I am still messing with that and know that my 60ft's will get better however the MPH seems low compared to some of the other F2 setup's that I have seen. Can anyone recommend a good crank and blower pulley combination. I am currently running a 77 tooth on the crank and a 44 tooth on the blower. Also what are most of the F2 cars running for gears? I am running 3.73's, with a Powerglide Transmission, should I change them? Any help would be greatly appreciated. Thanks! Drew
