forgot to say its a Clipper 250. not the one in the picture but the same engine.

There are lots of differences, including crankcase mouth size, barrel stud spacings, main bearing and mainshaft size differences etc. A better bet might be fitting a whole 350 engine in place of the 250, if it will go?
