{"product_id":"little-m2-small-block-chevy-iron-engine-block","title":"Little M2 Small Block Chevy Iron Engine Block","description":"The Dart Little M2 is a race-inspired, iron engine block designed for Chevrolet small block applications, featuring a 4.125-inch bore and a 9.025-inch deck height. It is constructed from 220 BHN cast iron for enhanced strength and durability, with Siamese cylinder bores that are extra thick (minimum 0.275 inches with a 4.185-inch bore) to resist cracking and improve ring seal for increased power. The block is built to accommodate standard small block components such as the cam, timing chain, oil pump, and oil pan.\n\nKey features of the Little M2 block include a priority main oiling system that directs lubrication to the main bearings first, an open lifter valley for improved oil return to the pan, and enlarged lifter bosses to accommodate offset and oversized lifters. It also includes blind head bolt holes that do not penetrate the water jacket for added integrity. The block is equipped with billet steel 4-bolt main bearing caps on all five mains, and it offers front and rear external oil feed, crossover, and restrictor provisions for simplified plumbing with external oil pumps. This engine block utilizes a 2-piece rear main seal and press-fit freeze plugs.\n\nThis product ships via truck freight and is excluded from free shipping promotions.
