Big M Sportsman Blocks

The Big M Sportsman block is an even more affordable version of our highly popular Big M. The Sportsman block is fitted with ductile iron 4-bolt main caps, and shares most of the feaures of the big M. For example, we redesigned the lubrication system to create a true priority main system that oils all of the main bearings before the lifters for extra reliability. We machine Big M blocks in-house on precision CNC equipment to ensure quality and to eliminate the need for expensive “blueprinting".

Chevy Tall-Deck Iron Big Blocks

The Dart Race Series block offers crank-to-deck dimensions of 10.600 and 11.100 inches - nearly one inch taller than the factory truck block - and can accommodate displacements of up to 763 cubic inches. The camshaft is raised .600-inch above the stock location and the main oil gallery is located alongside the camshaft tunnel to eliminate interference with the crank assembly. The oil pan rails are spread to increase clearance for the connecting rods and crankshaft counterweights.
