I was wondering if I would have any clearance issues with 10 cc dish pistons and a x303 cam? here are the motor specs: 94 302 block bored 30 over,Keith Black kb355 10cc dish pistons (9.7 c.r.), eagle 3.25 crank,eagle forged I beam rods,edelbrock rpm heads (1.90 valves,shaved 0.0015), x303 cam (224@50,542 lift), Crane 1.6 roller rockers,edelbrock rpm intake, holley 600 cfm vac sec. If you need more info let me know.
