So I’ve done a lot of searching on Google and the forms and I just want to confirm a few things. With the LS swap if I change the computer can I use the wiring harness from my 2.8 or will I have to upgrade to a 4.3 harness from a GEN2, and ECM?

I know about the radiator fans but if I upgrade the computer that means I can use a 4L60E or 700R4, correct?

What are the recommendations for upgrades other than headers and exhaust? If I get the engine from a junkyard with the intake to the air intake I should be ok correct?

I I think that’s it for now, but any advice, recommendations or tips are greatly appreciated!

Thank You
Glenn
