Choosing the right tire

[softballnrd27]

For all you racers, how do you choose the right size tire(slicks)? Compound?
I don't want to just guess and I know there has to be some formula to getting the right size and compound.

Here is some info on my truck so that maybe you can help me out here:
85 swb hopefully around 3600lbs after a diet
390" Stroker LS Iron block in the neighborhood of 450rwhp
AFR 230cc heads(box stock)
Port matched Vic Jr with 1200cfm 4150 style throttle body.
Custom grind cam
th400 backed by a 9" w/3.50 gears(will eventually have a turbo), Yukon locker and 35 spline moser axles.
Stock front suspension with appropriate springs and adj shocks, stock rear supension flipped w/caltracs and adj shocks

Help a brotha out!!
