Romper clearly has his facts wrong. GM never made a hemi to my knowledge. In '69, the Boss9 was put into street cars for the NASCAR homologation rules to try and compete with the 426 Hemi. Where was chevy in those years? Ford always was on the cutting edge of factory backed racing technology, and the Boss 9 engine wins the wow factor hands down...BigBlockChevys get boring after a while. Another engine that would be interesting to see in a boat would be the 427 SOHC, blown or not.
I have a 455 and already know what most people think of 'em. Makes me like it more.
