All I was saying was the 300 is a damn good engine, not everyone is able to swap out to a 600hp 514 stroker. Although I'd love to I really can't see that happening between my fenderwells anyway. I am however in the process of a 460 swap (still collecting parts). But the question was not what is the biggest baddest engine I can stuff into my truck, average joe wheeler doesnt always want a 2mpg or less offroad beast with 49 inch iroks and full blown race engine.
