Yes this is the original 5.7 that came out the car. Now I’m thinking about replacing the piston. Gapping rings and saving it. Anyone have a piston you’d sell me?Original motor for the car?
The engine i pulled out of my 04 when i bent a rod had gen iv rods/pistons. I guess GM started using them in some LS engines around 03 or so, and rumor has it 04 GTO's all did.
Makes me wonder if the motor i have now does. It came out of another GTO.
