5.3 or 6.0?
I am looking at converting to a new engine. Which is the better choice ? Rods difference? Wrist pins, piston?
Are there better heads to run from one or the other?
Planning on a S476 87mm 110 AR billet wheel. And holley hi ram

I would do a 5.3 and throw a huran speed kit or on3 turbo kit . Thats my plan when my engine ***** the bed. For like 4 k you could have 500 to 600 rwhp realiably and much more if desired.

Don't count out the 4.8L for boosted applications. If you are set on a 5.3, make sure you are actually getting a 5.3 and not a 4.8L. They share the same block, and are marked with both displacements. Pull a head, and look at the pistons. Flat-top are 4.8 and domed are 5.3.

Anyways, another good way is to look at the area with the 4.8L/5.3L embossment and the displacement should be marked with paint. For example, a 4.8L would have a shot of paint on the 4.8L embossment.

+1 for the 6.2L love mine. But mine is also a n/a motor. If you are going boost, and are on a budget. I would research getting a 5.3 and run 6.0 heads. I think I saw this set up in a 1500.
