There is a little flat area just behind the distributer on all GMCs. The first three digits tell the displacement of the engine. I wish the photo was clearer. No matter if it is a bored 270 or a destroked 302 the red engine in the car is a GMC. I saw a picture on yellowbullet that someone says was from this car that is a damaged later L6. Who knows if it came from the Pizza Man. By the way Edski I had a tough time getting past the dancing blond girl.
