Anyone happen to have a CB750 engine for sale?

I have a 1978 CB750F Super Sport, bottom end is blown so wondering if I can source a replacement engine and turn into a cafe racer. If I can't source an engine then I'll just have to part it out, which would be unfortunate.

I figured I would try this group before venturing into the honda forum world, I'd rather deal with the FJ people!
