Description:

Pulled out of a 2004 GTO, was removed to swap in a h/c/i 6.0L.

Odo on the car says 86k miles, but this engine was swapped in around 55,000 miles to replace the original engine in 2014. The donor car had mileage in the mid 40,000's. Based on that, the engine has approximately 75,000 miles on it now. I have driven the car with this engine for 6 years no with no issues.

Car had only bolt-ons installed before the engine was pulled.

The engine comes with no accessories or manifolds. What you see on the engine stand in the picture is what is for sale, minus the oil pan. I can provide a summit racing steel pan and matching sump if you need a pan.

The engine is a 2004 year model LS1, out of another GTO. It has It has gen-iv type connecting rods, pistons, and floating wrist pins.12561168 block casting number. 241 casting heads, ls6-style valley cover. Comes with an SLP harmonic balancer. Engine is internally stock. I have tried to take a picture showing the bottom of the rods, but i am not willing to pull the windage tray or sump at the moment to take additional pictures.

Below is a link to a video of the engine running, vcmscanner logging, which shows oil pressure, fuel trims, and a few other basic PID's. It was taken right before the engine was pulled.

The passenger side head has some scratches on by the #4 intake port. I am not sure what happened here, as it was this way when i purchased it. Never had an issue with the intake manifold gaskets sealing, however.

Pickup preferred. I may be willing to drop off within a couple hundred miles of my location. Any farther will have to be a frieght shipment and shipping costs would be substantial.
