What gears should i run?

With that cam your peak power can't be much more then 5500 rpms.
26 inch tall tire and a tight convertor??
I would leave it alone and shift it like a two speed in the quarter, going past your peak power by 400 rpm and reving it out in second.
It will hook out of the hole great with slicks.
2.76 gears are perfect with your cam.
your cam is a lower rpm cam that makes alot of torque.

If i had to choose then i would use 4.10s with a better cam.
put a nitrous cam in it with the new gears,
OR JUST LEAVE IT ALONE.:thumblef:
HEY,IF YOU CAN RUN FAST AND HAVE 3RD AS A OVERDRIVE ??? :drinkers:

What do you have to lose,it's already put together in your drive way.
