Let me expound a little. I am not an engine builder. I have a buddy who built my last one that lasted 15 years of my abuse. I have two scenarios. One is a pretty much stock build with a mild cam, better pistons, lighter flywheel, much more free exhaust. The other option is to raise compression, aftermarket complete fuel injection system, extra machine work, same exhaust, more radical cam, etc.
Machine work, headers and exhaust, and some things will be close to the same either way. I'm looking for a simple way to compare the two and decide on the final product.
