Iam have a 1964 C10 with a 385 stroker and a NOS cheater system it is putting out about 650 hp with the nitrous and about 425 without the juice. I put a T-56 six speed trans in it for the highway cruise and a 4.56 gear in a 12 bolt posi rear end. I also put all viper internals into the trans to handle the torque of the stroker.
