Here's what I did on my 493 stroker:
4.15 crank
Ross dished pistons, 10.6 Compression
Ported Eddy RPM heads
Racer brown cam STH-42
Roller rockers, 1.7-I 1.6-E
Ported sd holley intake
850 Speed Demon annular carb on nitrous plate
TTI headers 2" primaries
Idles at 900 rpm, This thing pulls incredibly hard and sounds wicked. I'm still not ready to turn the nitrous on.
