??? The cam is the brain of the engine. How can you say that? Without the cam you dont know what intake runner length you need or header tube size and length. Power band dictates what stall you need and the camshaft is a major player in determining the power band. I should have been more clear on my description but I wasnt wrong.
You have to match the engine. You need to know what RPM you want to turn the engine. Then figure out what heads its going to take to feed the engine with the RPM in mind and what HP your shooting for. Once you know what heads and what RPM only thing left is picking the camshaft. Rod ratio has very little effect on peak power. Then ideally you will dyno the engine to know where the peak power is and pick you converter accordingly.
