Ive got a 65 stang and Im rebuilding the motor.When its all said and done it will have speed pro hyper. coated skirt pistons,total seal claimer(gapless) rings,a comp cam 512/512 roller cam,roller lifters,1.6 roller rockers,double sprung valves,351W heads,double roller timing chain advanced 4 degree's,mallory ignition,edelbrock performer intake,edelbrock 650 carb,stock manifolds,flowmaster mufflers.Ive ran the numbers on desktop dyno and it said around 298/320 but i think those are a little high.And If I had the cash I wouldve put different heads and different manifolds.
