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. - Dart blocks are available fully finish prepped.
