NEW setup
If you have a 28" tall tire AND you are running 1/4 mile, then the 4.56 is probably a little too high. If you are running 1/8 mile you're fine. The gears will work but it will be wound up pretty tight. I have 4.10 gears in mine with a 28" tall tire and it is about 6700 ish at the stripe (1/4 mile).
I don't understand the statement that "money has been tight so i used the 308 heads", but then you add a custom cam, Caltraks, split mono's, 9 ways, trans-brake, 2 step....but hey, everybody is different....I just would have spent the extra 1500+ dollars on good heads. It should be a fun ride regardless, my guess is low 11's 1/4 mile or low 7's in the 1/8.
