Sure John,try and blame me for your addictions.LOL:wack:When I raced my 4 speed car,it was a learning experience for sure.You,ll have to see what your car likes.Start off with say a 2000rpm launch and see how it likes leaving,then work your way up.My friend races a 383 alumi heads and has rev limiter set at 6500.Post some times once you get done.
