Welcome, do a search for LS swap or Holley LS swap here on the forum. You’ll find lots of good information

The holley ls gbody swap parts are the way to go. It seems expensive until you get it all done and realize you didn't have to modify anything to make it work. No countless hours searching junk yards and want ads for hopefully the right manifold or mount. Do yourself a favor and spend the money upfront. I just did a ls1 swap on my 79 cutlass over the summer. It was super easy and turned out great.

You could be different and go the newer ls based 4.3 like this.

Saw that on the faceballs... definitely unique.

I am planning a LS swap as well and I second the Holley suggestion. I have searched and even though it’s a little more money it is made specifically to fit so there is no second guessing.

My BIL had one that looked the exact same. Except his had a roller cam 305, with better exhaust was a decent performer. Old man owned, so not worn out. Your 4.3 V6, probably not so much. Good luck on the swap, there should be a step by step tutorial somewhere, done a million times.

Copy and paste from a previous post I made a few months ago-


The holley kit works well but is engineered to make holley money. If you want a drop in solution its a good option, but there are other ways to do it that will save money.

That extra $200-$400 for holley parts may or may not be worth it depending on your abilities, budget and interests.

My favorite I have seen is

CTS-V oil pan
Spohn swap mounts
4th gen F body block mounts
Stock pickup accessories

Allows stock AC pump location which is a huge win.

The speed engineering G body LS swap headers work well in that application from what I understand. Stainless too.

In regards to the speed Engineering headers, I'd say they would fit darn near perfect with the Holley system. I have them with swap plates which put the motor back further, and had to ding the fire out of at least one tube on each side. Other than that, they are amazing headers for $275, sound great, and look badass as they've started changing colors.
