Yes most of the exotics are OHC because of their tednecy to be high-revving, top end oriented motors. But there is no one who does pushrods better than GM. DOHC mtors have been used in performance GM cars. They have the Northstar motor but GM won't use them extensively because they cost too much. GM has to build to different price point otherwise it will end up making a car like the Corvette ZR-1 which was much too expensive. The LT5 was a 5.7L DOHC motor that was very powerful but too wide and too heavy.

I do agree that the MOD motors respond very well to forced induction.
