DA31192211 - SBC LITTLE M2 SPORTSMAN BLOCK
Part Number: DA31192211
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.
Features
Uses standard small block parts, including cam, timing chain, oil pump, oil pan, oil filter, motor mounts, mechanical fuel pump, and clutch linkage
Priority main oiling system feeds the main bearings first
Siamese cylinder bores with extra thick walls resist cracking and improve ring seal for more power (minimum .275" thick with 4.185" bore)
Scalloped water jacket walls improve flow around cylinders for better cooling
Open lifter valley improves oil return to pan
Enlarged lifter bosses accommodate offset and oversize lifters
Blind head bolt holes don’t go through to water jacket
Splayed outer bolts on middle main bearing caps
Rear external oil feed, crossover and restrictor provision
