The Dart Little M is designed from the ground up as a true racing engine block which 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.

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 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).

• 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.

• Billet steel 4-bolt main bearing caps on all 5 mains.

• Front & rear external oil feed, crossover and restrictor provision to simplify use of external oil pumps.

• Parts kit included (PN 32000001)
