I have a 2003 6.0 out of a 2003 SS Silverado and a 4L80E trans. Any performance suggestions I should do prior to installing it. The engine has 80K on it and the trans has 107K on it. Think I should have em freshened up a little prior to install or just get it on the road for now? I know I wont be the fastest so not worried about big HP #'s jsut would like a good sounding engine with 350-400hp in my 59' This engine is supposed to be 345 so the hp isnt bad just not sure if I should put a thumper cam or something in it. Any suggestions would be appreciated.
