I don't know for sure, because i can't find it, but I'm guessing it's a 351M or a 400. The casting number you did leave tells me it's a design that changed in 1977, and that it was originally a truck engine. The 302's and 351W's didn't undergo any major revisions in '77, but that's right around the time the 351M & 400 were busy.

You need to look at the front of the engine, where the timing chain goes. Cleveland engines have a cast into the block chamber for the chain and gears to sit in, whereas the Windsors have a timing chain cover. See if you can tell which one you have.

Take care,
~Chris
