Info

True race block which will work with most standard components. Provisions for wet or dry sump oiling systems. Great for power adders and maximum effort engines.

The Dart Little M is designed from the ground up as a true racing engine block that can be used with standard off the shelf small block components.

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. Front and rear external oil feed, crossover and restrictor provision simplify plumbing with external pumps.
