Looking to build a motor for my next project. I found a 6.2 shortblock rebuilt for a little over 2k but would still have to buy heads, cam, intake, acc., etc etc. 6.0 are alot easier to find and the 6.2 im sure will cost more to build. What would be the pros and cons to each. And which would be the best bang for the buck. I know SilverSleeper s truck made almost 400rwhp witha tune, drop in filter and exhaust.
