LS3 in 69

The wiring should work, but are you considering the GMPP package with harness, pedal, ecu?
If so, check over on LS1tech conversion board, it seems the GMPP ecu is locked and not the best choice for any mods.
It might be cheaper to modify an existing harness and have the ecu reprogrammed.

I am putting a LS3 in my 72 and used a custom harness from PSI. Not in yet but the harness is top notch and I am using the LS3 computer that has been reprogrammed. Cost was not that bad either.

Can you share info with me about your motor change out? I have a 69 thinking to do the same.
