raced a lt1 trans am tonight in my abody!

If you're spinning a 295 x section tire, I'd say the biggest thing you need is traction. But, if you don't spin, you'll lose RPM...which means you need some gear. I know Hot Rod beat up a 70s 318 many moons ago with nitrous. I think they got to either a 150 or a 200 shot before it finally spun a rod bearing.

I'd add, if you're spinning now with a mild 318, you'll need to buy stock in Goodyear to keep that thing shod when you finish your 408...
