[Task Force Era]

Probably not a very popular question.

But I have a 03 Silverado short bed regular cab with a blown up 4.3. I've thought about LS swapping it but I'm probably not gonna keep the truck so I scratched that idea.

So to my question. I can get 2000 and up model blazers dirt cheap at my local insurance auction with 4.3's. So will those model 4.3's work in my 03 truck??
