what are my options for performance i have a 97 jimmy 4wd i want to keep the 4wd or point me in the right direction to any good shops that specialize in blazer/jimmy's i'm new to them so i dont know a lot

The first things you could look at is a cold air intake, a cat back exhaust, and a pcm tune. Also maybe some headers.

V8 swap.

NOS kit.

could i do a v8 swap and keep the 4wd if so what are my options

i'm also looking into turbo
