Im not sure what kind of comparioson this is supposed to be, an early engine saddled with the crappy dual plane intake and a cam of what size ? VS a later engine with better intake and EFI...

Im confused but I would think a more meaningful comparison would be to stick a stock early motor with the factory EFI controled by holley VS an eagle engine controlled by holley, if your gonna saddle one down with a crappy intake do it to the other also.
