The Little M is designed from the ground up as a true high performance block which can be used with standard off-the shelf small block components. It is cast from premium high-strength iron and beefed up in all the critical areas. With a standard deck height, extra-thick 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. You can select 4.00" or 4.125" cylinder bores, and 350 or 400 main bearings. Front and rear external oil feed, crossover and restrictor provision.
Sportsman blocks have nodular iron main caps, center 3 are 4-bolt and ends are 2-bolt. Cam bearings, freeze plugs and dowels are not included. Machined with rear external oil feed, crossover and restrictor provision.
