Overview

Cast from premium high strength iron and reinforced in all critical areas, the Little M Pro block offers several cam upgrades and a lightening option to take the standard Little M design to the next level for the serious competition engine.

Features:
- Extra thick cylinder walls resist cracking and improve ring seal for more power (minimum .275" thick with 4.185" bore).

- True priority main oil system lubricates the main bearings before the lifters. Our stepped main oil gallery (9/16" to 1/2" to 7/16") increases the flow of oil to the crank at high rpm, and our front oil crossover eliminates internal oil leaks around the distributor shaft.

- Scalloped outer water jacket walls improve coolant flow around the cylinder barrels to equalize temperatures.

- Blind tapped head bolt holes prevent water leaks.

- Extra thick decks ensure reliable head gasket seal.

- 4 bolt billet steel main caps have splayed outer bolts for extra strength.

- Open lifter valley improves return to oil pan.

- Enlarged lifter bosses accommodate offset and oversize lifters.

Block Prep Options
Dart blocks are optionally available fully finish prepped. If you choose to order your block this way you can specify a final lifter spec and a final hone spec. Your block will be finish machined to your specs, final prepped and washed, pipe plugs and freeze plugs will be installed, then it will be bagged and boxed. Your block will arrive finished and ready to use!
