Thanks for the input, guys. I will get out to the storage building in a few and shuffle things around so that I can get to the side of the block to see if I can get some more #s off that block. It is sitting upside down, against the wall and surrounded by who knows what. Hotrod, I will definitely consider making some sort of swap if it does turn out to be a GMC engine (which I'm pretty sure it is now). Just got to have some time to shorten the Honey-do list, so when I disappear into the shop, there are no bad consequences!
