Nah, that is a small block Ford(oil filter mount and motor mount bosses give that away) in aluminum with screw in core plugs, steel cylinder liners and roller cam bearings. Looks like a Dart block. Saw a number of images of this one some years back, and I do believe it was just a wee bit too much nitrous. Saw it on a drag racing site.Looks like a forged Internals LS series engine that may have seen too much of a power adder.
Send it to Doc. He can rebuild it good as new.
