I wondered if anyone out there had an opinion as to which GM crate motor would be better. For my purposes, I have narrowed it down to either the 330hp 350 or the 370hp 350 with the roller cam. My initial thoughts were to get as much power as possible but now I am thinking the lower horsepower motor might be better suited to off road. Does anyone have any experience with either of these motors. Will I really miss 40 horsepower if I go with the cheaper motor? Are there any advantages one way or the other that anyone can offer? Thanks.
