Product Description

Dart's Little M Sportsman block is the affordable alternative for Sportsman racers and serious street performance. The Sportsman block shares most of the Little M's best features, but saves you money by using Ductile Iron main bearing caps (4-bolt on the center three and 2-bolt on the ends), and employing a rear external oil feed, crossover and restrictor provision.
