Re: 4.8 vortec LR4
And by the time he's done buying all that he could have had a 6.0L, probably with money left over.
My '02 truck had a 4.8L and it was an impressive engine. Towed my Z28 plus a ~1200 lb tare wt trailer like it wasn't even there.
I'm not saying don't get the 4.8, just price out a 5.3 and/or 6.0 and make an informed decision.

C'mon Pocket, look at the guy's join date. There's probably not even a car, forget about a plan...just a pile of magazines and Summit catalogs.
