bored .40 over
heads are gm performance cast iron with 2.02 intake and 1.74 exhuast and yes its 1.74
intake is a edlebrok rpm air gap intake
carb is a holley 750 double pumper
ignition is a msd distributer and a msd 6al2 ignition box
exhuats is dynomax headers with flowmaster exhuast 2 1/4 pipe
cam is .520 lift
flat top pistons

if u have any ideas how much hp i have give a guess i will dyno it when i can find one near me lets c who can get closest

Need more data. 1.74" exhaust valves won't fit in small block heads. They're probably 1.6". What is the chamber volume? Piston head type? What are the duration numbers for the cam (@.050 lift)? Lobe separation?
