4.8 swap opinion

[Dmax21]

I've been looking at all the Ls swap info and everything is about a 5.3, now I got a really good deal on a 4.8 engine and transmission and wiring harness, now is there any reason I should not do the 4.8 and hold out for a 5.3? My goals for the truck is a dependable driver with more power than the tired 350 and of course get rid of carb. I hadn't put much thought into it but it seems nobody or at least not many have done the 4.8. So whats you guys opinion.
