5.3 advice
I purchased my first 5.3 today and thought i was purchasing a garden variety LM7 but ended up with an L33 with 799 heads. I plan on putting a procharger on and though it has been beat to death I still have yet to find an answer, iron or aluminum for boost? If i were to sell this l33 (60xxx) miles, what would it be worth, not intake manifold or computer?
