i am in the thought process of building a big block. ive talked to a lot people, (sometimes we were both drunk you know how that goes) One guy swears up and down that a 427 is the way to go, Another guy suggested a 396, and 454 is just a give in. I kinda want either the 427 or 396 just to be a little bit different. What are your opinions? truck is mainly trails and rocks, occasional mud bog. plus id like to be able to get off the line a little quicker when me and my buddy in his ford are at the stop light together.
