5.7 uprgrades

I just recently picked up a 97 1500 with 51k miles on it. I had a 5.3 and did some performance upgrades to that, but the 5.7 is a new world to me. Where do i start, what should i do? It has dual exhaust nothing special, also wondering how to get rid of the moderate cackle if even possible. I wont be doing anything serious, like boost. My 5.3 was a 03 Tahoe that was lifted with 35s and had long tube headers and dyno tuned. I know that will be a stretch to get a 5.7 to that point, but what are my options?

TB spacer, cold air kit, pulley's, long tubes, nitrous, and boost. But they really don't respond well to boost. Engine swap would be ideal.
For the cost you of doing the above you would have funded a ls based swap and have a better platform.

What kind of power are you looking to make? If your looking for around 350 hp you would be better just doing a swap.
what I said at the end of my post.
