What mods do you have? And what height tire are you running? Those determine gear choices more than anything

Best for blowers IMO is the 3:73's. Especially with a T-56. I am running 3:73's right now in my 2 valve with a T-56 and its the shizznit. :headbang:

Id honestly stick with the 3.55s

Unless you are a track whore, then Id say 3.90s if you're running 28s or 3.73s with 26s.

You are already making a LOT of power, what Hank said, stick with the stock gears unless you're a track whore. If you did 3.90's, imagine your first gear being just like 2nd and a little in 3rd. 1st gear would basically be useless unless you feather it.

is it worth doing lower or just wait to the heaton goes out and switch to a twin screw?

Lower pulley will bring your HP and TQ numbers closer together. If you do a lower, I would do a 2# lower and a retune. Sounds like you have a strong car already though. Plus when you start messing with the lower you start messing with alternators and alternator pullies!
