Actually no,

Its the same size crank case as the .16 as all other .18 engines. The difference between the .18 marine engine and the one in the picture is the construction of the piston and sleeve. The Marine engine is nickel plated. This one is True ABC construction. And yest it has a nicer cooling head. Quite attractive imo. This engine is quite powerful, out team drivers are very impressed.

It will fit any where a small block engine will fit. Perfect up-grade for .12-.16 trucks, cars etc.
