So took a close look at the engine. Looks alright. Block number check out to be a 55-57 261. The head is actually a 848 one already so things are looking up. Can be turned over by hand so it not seized. Oil pan looks to be in mint shape and also got a second valve cover with Chevrolet stamped into in like what the corvette has. Guy might even have a second 848 head he will toss in.

Only thing is that his buddy took half of the valve rockers frown

Great guy....he actually is just giving me the engine and stuff for free.
