the 408 is nothing crazy. It has a scat rotating assembly which I believe is 9 and a half or 10 to 1. Comp cams xe 268h cam and lifter set. J heads with 1.88 and 2.02 valves and minor porting work. I was told it should be around 425 horsepower and 450 to 500 ftlbs of torque. will the tf2 kit make the transmission shift harder? Or any transmission shift kit for that matter? The car is going to be given to my parents and I don't want it to drive to crazy
