My dad recently bought a 454 for 400 bucks, and I say recently, it was about two hours ago, and the guy said it was a tall deck block out of a dumptruck. Well, he wasn't playing with a full deck because it's clearly not. The number on the bellhousing area on the driver's side was 361959 with a big P underneath it. Number on the intake was 465899, and passenger front near the water pump hole was C9B130518. I have no idea what these numbers mean, but I do know the 361959 means it's a 73-85 car/truck block. Any help is appreciated.
