Yep, appears to be the same block. Just saved the engine images from both the previous and this thread. Side by side the wrist pin orientation and a few other details look to be the same. Nice find and I'd love to have it in the shop for a upgrade for my '51 216 truck. As Jerry previously mentioned, a lot of the missing bits can be supplied by a 235 engine.
Good Luck Rick!
