Hey I'm looking to replace my old 168 tooth flywheel off my 72 C20 and replace it with a externally balanced one for the new engine, which is a L31-r/5.7 vortec. I would like to change the clutch while everything is apart. I have a 12" clutch that was pulled out of it. I'm wanting to go with a cast iron flywheel because I don't really need a steel one I don't think. The only flywheel I really found that is to these requirements is the perfection flywheel.
