Billy, I felt like I was doing it right... Back then I was dead hooking radials, weighed about 3400 went 1.34-6 60' a few times then snap. That was the end of 30 spline stuff. I had less power than the OP is claiming. I switched to 35 spline which stayed in the car for my new combo... the axles are stronger than the spool, on Jacks noticed I could roll one tire before the other one would start. This combo is lighter, a lot faster, and depending how aggressive we get it sometimes dead hooks the radial.... would be fun to race the OP, both are NT cars I believe
