i managed to run a 14.2 w/intake,exhuast,hi-flo cats at my very first time at the 1/4 drags ever in my life. I think if i go a few more time i can do 14.0. ANd possibally loose some fat i MIGHT dip into the 13.9. I believe after header install i will hit 14.0 and might hit the 13.9. Then if i loose some personal fat again i might hit 13.8?
