[QUOTE="millerxc, post: 83887, member: 495"] I found out a stock 5.7 vortec will not last long against the rev limiter, ovaled some rods in mine and instead of going back stock I did the 383 using Eagle rotating assy, and put a GMPP cam with roller rockers and a little more comp than stock, and had the comp tuned, overall spent about 1300$, definately makes more than stock but I'm a little dissappointed, I've always run BBC and this motor still has no low end, I am going to put a little stall conv to see if that helps cause it is real strong in the mid, overall it is probably the last SBC I'll use in a 4x4.
