what are you planning to run for a motor and tranny? what size tires? is it going to be just a drag truck or somthing that you need to drive to the strip as well?

if its an automatic with no OD, then its probably a 727.

What rear axles are you going to be running as well?

I'd run 4.10 or 4.27 gears, depending on the axle that you have, as they will give you a good solid launch but won't kill you on the road. I'd also throw in a posi unit or a spool. posi won't beat on your tires as bad as a spool will, but both of them will greatly help out with getting down the track.
