    Why the troublesome 5.7 Vortec? Go for a Gen3 engine, 4.8, 5.3 or 6.0L. It will cost just a little more for a lot more dependable HP.

    trust me guys i would love a 5.3&#33;&#33;&#33;&#33;&#33; all day long but its a bit much for me to afford with paying for college and all im only 18 and this is my first swap wont be my last and who knows im sure someday ill go for a gen 3 or w/e else is out there but for now the 5.7 vortec will be good enough for me im still learnin haha taking into consideration that just abou everything in the GEN 3 motors is much better i just am not quite that skilled yet but thanks for the encouragement plus i already have the 5.7 motor sittin in the garage haha

    X2...you can put just about everything on a 5.7 and just maybe break into the 14s...with a 5.3 and tune alone you&#39;ll be in the 14s for sure.
