just wondering if someone could ballpark a guess at how much my 83 z28 is pushin?
. The original 305 block was bored .030 over, hyperteutectic flattop pistons installed, block and heads decked, Edelbrock Performer intake manifold with Edelbrock 650 cfm carb installed, and an RV cam put in from Crane Cams. hooker shorty headers..... and wut else could i put into it to get a little more out of it

 

Hard to say without knowing specifics about the cam. "RV cam" usually means low RPM range, meaning not much power. You know, like a stock cam.

You probably have about 175 net HP, like engines are rated from the factory.

Any particular reason for the choice of carb? If it originally had the computer controlled q-jet, you'd be better off with it.

 

no it was the plan old stock carb b4..... i found an old dyno from previous owner....... 290 torque @ 3500rpm
222 hp @ 5000rpm

not sure in what stat the engine was though
