If you had a rcsb 5.3 and money was not an object but you wanted to build a 5.3 instead of dropping in a 6.0, what would you do?

forged internals?
huge cam?
aluminum heads?
There are a ton of options out there.

What would your ultimate 5.3 be? The purpose of this is to see what types of ideas people have as far as getting the most power out of a 5.3 instead of just dropping in a 6.0. I think answers not involving FI would be better but hey its your ideas right? What would you do to make the most powerful NA or FI 5.3?

I'd bore it out to use ls1 pistons, a good cam, high flow heads, and high compression. That's after all bolt-ons, exhaust, etc.

forged internals (Eagle setup most likely) with a set of AFR 225's, Big cam, something like a 232/240 or so with close to .600" lift.

use the block and make a 383 out of it with some ported AFR 205's, Vic Vr intake 90mm TB and about a 234 cam, 4200 stall and some 4.56's... dont forget the 300 DP shot of N2O
