LM4 mod suggestio for project Goldmember

So this weekend my son brought home an all aluminum 5.3 (LM4) for my project Goldmember Suburban.
Curious to see what you all think I should add/ modify. I'm not looking for anything overly aggressive on this, just not stock.
I'll most likely run a 4l60 and keep the 3.73 gears
Just thought I'd ask here too as I begin my research


Thought?

With a good tune the LM4 runs pretty good for a driver/cruiser. They have good heads on them, a pretty good cam, and intake too.

Cam kit (springs/pr's/guides) and a tune with a good set of manifolds or headers is really all you need to get cruising with a lil more power.

If you need more than that, you can consider a small shot of n20 without changing much at all.

Or you can consider running a slightly more aggressive N/A setup, and using methanol to keep it fun on pump gas.

Thanks,

that is pretty much what I have found most everyone suggests as well. Looking forward to getting after this..
