383/489 Stroker

I ran a 260-264 @.050 solid flat tappet in my 470 on the Dyno and it peaked at 5700 rpm.
That cam in a bigger engine will definitely be a street ripper but your peak will probably be 5000-5200 and 600 foot pounds at 3000 rpm, just a sorta educated guess. Buy 3 sets of rear tires at a time lol
