engine differences

Great question. The Romeo and Windsor engine's have different amounts of cam cover (valve cover) bolts. Windsors have more. The Romeo piston has a fixed piston pin and smaller connecting rod. The Windsor piston has floating piston pins and bigger connecting rod. I really do not see any other functional differences or know of more. If I had to give the edge it would be to the Windsor, but I truly feel there is no real functional advantage to either one.
