How much power are you aiming for? What will the engine be used for? How about internals - What's the compression ratio, pistons/rods etc? What fuel are you going to run?

hp wise 500 to 700 i want to use a smaller cam so i have some street drivabilty / street car/ toy / i have 3 small block motors to play with / all steel crank / 4bolt main blocks and forged pistons and good rods , c/r form 8.5 to 9.5 afr heads or brownfield or gm / roller solid cam / want to run pump gas . thanks for your input dwayne
