Hello,
We need to do an engine swap in my son's '04 Colorado..head valve seat problem. I have been told the '07 engine is the way to go as it's an easy/almost direct "plug n play" swap.
How can I identify the engine from an '07 if it's out of the truck.? Where is the number stamped and what designates an '07 year??
If you have one for sale, let me know.
Thanks,
Bob
