I would look on Summitracing.com — they have stuff for the 4.3. vortec. I wouldn’t try to go too wild with it. There is only so much you can do with the 4.3.

Alright thanks do you recommend anything specific for it?

Mostly top end stuff. Cam, intake and possibly heads. But those heads are probably the vortecs just like the 350 version. The heads will need machining for more lift for an aftermarket cam if the cam is going more the .450 lift. There’s a lot of details when it comes to getting vortec heads ready for a performance application. They are good heads though.

Also a set of headers and exhaust. But 4.3 v6’s (and any american 90 degreeV6) sound like poop to me.

You will also need to get a tune to take advantage of all those mods.

I was actually thinking all off that then long tube headers with dule glass packs dumped at the rear axle or possibly an H pipe set up
