K I took my motor apart cuz it was overheating and it turned out to have cracked and warped heads. So I got new cam and heads and want to know a hp estimate. It's a first gem sbc with stock crank. It's bored 30 over. it has edelbrock performer rpm cam with edelbrock valve springs. It's got TBI heads edelbrock air gap intake. Edelbrock 650cfm carb. Pacesetter headers and full 3" exhaust. Just won't a rough hp estimate At the crank.

Are you talking about a 350 small block?

run the car at the tracj and tell us your time.. its easier that way if you have a race weight too.

on a friendly engine dyno i would think around 375-395. not too sure about the heads . with a good set of heads that flow in the 240 cfm range at your lift id go 400-415 hp range. hope this helps.
