Is a lightened flywheel overrated? (I think so)

[ctlikon0712]

This is a subject that I have thought allot about also. I have tossed around most of the pro's and con's mentioned minus Mike K's dissertation... wow Mike that is an interesting point and read.
I learned a long time ago on Rochester Quadrajets that if a company puts many hours and even years of engineering into a product, that you’ll usually get more out of using the design as intended than throwing a "Holley" on it to make it faster. That is unless you plan on spending years and allot of money on research. I plan on leaving my car's engine alone except for a maybe a higher compression head. My car is a woody and heavier than most.
