willa 5.3 fit into an 01 blazer? Or is there any mods to do to the 4.3? My brother just picked one up and I have my old 5.3 on my trailer

I'm not gonna say it'll just slip right in, but you can make it fit. I haven't really seen to much for upgrades on the 4.3, but I haven't done much looking either. You'd have to probably go with some of the block hugger headers to make that work, but I guess it all comes down to how bad you want it.

There are parts for the 4.3, but they are pricey cause of the low demand, and at the end of the day you have a v6 with a lot of coin in it that still wont keep up with the v8s.
There have been literally billions of v8 swaps into blazers and s10s, I see no reason it couldn't be done. Like he said wouldn't just fit right in, and would have to change the radiator for sure for clearance and cooling, have to go electric fans, maybe even on the front of the cooling stack for clearance of the engine to radiator.
My bet is that you could buy everything to do it ie mounts and adapters and such, wouldn't even have to fab and refab, and refab, you get the drift.

You'll want to check the Conversions & Hybrids section over on LS1 Tech. Just click the tab on the Top Left of this site. They have a lot of similar projects.
