This is a 2001 Cadillac STS converted from the Northstar engine to a Series 2 3800. It's an unfinished project; engine is running but I'm having issues with the Passkey 3 security system plus it needs a few things finished up and some electrical issues figured out. Engine is in excellent shape; low miles, very clean and runs great. lots of new parts installed during the swap. I had a speed shop reprogram the PCM to match the Cad VIN# and accommodate the 4T80 trans. The car itself is in great shape, body, paint, interior all very nice, good 17" tires. Also have a stack of wiring diagrams. and the original Northstar engine (cracked block) to go with it. This could be very cool if finished or put it back to original. NO RESERVE!
