The Little M is cast from premium high strength iron and beefed up in all the critical areas. A competition oiling system ensures adequate lubrication to the main bearings at high rpm. You can select 4.000” or 4.125” cylinder bores, and 350 or 400 main bearings with steel 4 bolt main caps. Front and rear external oil feed, crossover and restrictor provision simplify plumbing with external pumps.
With a standard deck height, extra thick siamese cylinder walls and a competition oiling system, the Little M is the perfect starting point for a powerful and reliable engine for the street or the race track.
