Stock suspension drag racers step in please.

Unless it's a 1/8th mile drag car only you probably don't need anywhere near the gear you have now. I've seen a lot of real fast 1/4 mile stroker combinations running 3.91 and 4.10 gears with 28" tall tires. I have a real mild 408 in my Cuda and it's a long shot from a drag car but still runs real low 12's on cheap Nitto drag radials with a 3.55 gear. I think taller gears and taller tires will not only make your car much more streetable but hook much better. 340's love those short gears but strokers are a complete different ball game.
