Thanks Quenton. I was hoping you would chime in here. I am going to run out there tomorrow afternoon to take a look at it. Should it have 428 cast into the side of the block? If you don't mind I will post the date codes tomorrow when I get home. I printed out all the block and head code sheets from Pontiac Power. Maybe I will get lucky and find a diamond in the rough. He actually said it is a 428 HO. Worth going to take a look at.
