I have an idea. I was wondering if a 4.2 crank with the counter weights on the crank machined down to reduce rotating weight would work in an engine limited to say 5500 rpms. Could the crank be treated to be stronger or harder? They are only around $250 new from Ford. Seems like an easy way to gain power if aluminum rods were used. Any imput would be helpful. Tim
