Hokay... first off... yes... I am crazy… second... well I guess I didn't think of a second thing... hmmm (see first point)

So down to the task at hand.. a swap thats been kicked around more than that stray soup can that you kicked when you were a wee little one.

For simplicity I decided to go the LS4 route because a few members here said that it will bolt up to the 4L30E so I won't have to put in a different trans and complicate things more.

The mechanical should be pretty easy.
  • Motor mounts
  • Make a starter mount bracket to mount the starter on the engine.
  • Install diff drop brackets.


The electrical is a bit harder.
I was talking to a guy on the LS1tech forum and he said that if I find the wiring diagram for a 4L60E trans then I should be able to match up the 4L30E wiring to a new plug and play harness that uses the 4L60E. I would just have to get the ECM tuned to run the 4L30E.

I printed out the diagram for the 4L30E and I found out something interesting…. I have no idea what the F@^$ I'm looking at.

If I install the 24X LS4 then I don't have to change over to DBW so I can retain the cruise control.

sooooo if anyone would like to offer up some advice on the wiring, you'd be doing me a huge favour.

thanks,
