I'll eventually get one of these valvebodies from CRT so I can launch in 2nd gear. It's a cheap alternative to a powerglide, which is what my car really needs. I have way too much SLR for a 572" motor on nitrous. Leaving in 2nd gear would really help get the car off the line without incinerating the tires.
