Stock suspension drag racers step in please.

Less gear and a taller tire. Drag radials don't like tracks that aren't well prepped, so you my want to consider a bias ply tire. Also, the stroker won't need anywhere near as much gear as the 340 did.

For what it's worth, my stroker is backed up by 4.10 gears and 28" x 11.5" Hoosier Quick Time Pro tires. No traction issues at all, street/strip, mid 10's.
