That would be the ideal route for me, Im looking at the vrx5 cam, but wouldnt I need valve reliefs if I go with 5.3 heads?

Interested to see how the swap process goes. I've been looking into swapping mine for a couple years vs building the LT1 and decided I'll try to find a whole donor car for harness pcm dash accessories ETC.
Yeah, Im Staying NA, but im not looking forward to trying to gather up all the pieces I need and spending the money haha, im not sure What Ill do as far as the wiring harness goes yet, Ive read about guys modifying the stock lt1 harness to work, some say its not bad, theres a guy on tech thats helped a few guys out with their harnesses, maybe I can get him to do one more lol

Your harness wil not work at all. You will need to swap to atleast a 1994 up interior and engine hraness. The 1993 harness is bank fired NOT sequential like the 1994 up and ls1. So your stock harness is missing 8 extra wires as each bank only has one wire to fire the. Injectors on each side. It would be a nightmare to do it. And the ecm connectors are different and because of that the wiring is not long enough to reach across the newer style conector pcm's. Have a harness made for your custom app. Through efi connections or get a donor car/all new harnesses. 1993 is notttt easy. And your tranny will not work as it is not pcm controlled either. Not to mention the bolt pattern. Hope this info helps. If you need anymore I got it. I was doing this swap(kind of) with my 1993 t/a.

I know the tranny wont work, but I need all new interior from a 1994 and up car? I was thinking switching out just the cluster and leaving the rest.

The wiring from the engine harness to the interior harness is different. As well as the cluster that runs to the gas tank and the gas gauge won't work either. Ls1 fuel level runs through the ecm. Those wires are not in the engine to dash dash connectors.
