Type: Engine Block
Vendor: Dart

Description:

The Dart Little M SBC block is a 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 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.  The available sizes are:

Mains: 350 and 400
Deck: 9.025
Bore: 4.000 and 4.125

It comes in three main types: Little M, Little M Sportsman and Little M 305 Water as described below. 

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).

The Dart Sportsman SBC block offers many of the standard Little M features but at a lower price point.  The savings are achieved using ductile iron main bearing caps (4-bolt on the center and 2-bolt on the ends), and employs a rear external oil feed, crossover and restrictor provision.

In order to accommodate the needs of racers in classes that require engines with stock displacements, Dart is now offering a Cast Iron Little M 305 water block with 3.750” cylinder bores. Legal for 305 RACESAVER® Sprint Series.

The new Little M 305 water block has non-siamesed cylinder bores, priority main oiling and thick decks with blind head bolt holes that give the Little M block its reputation for reliability and excellent performance.
