Dart "Little M" Engine Block

The Little M block is the affordable alternative for serious small-block racers. Our precision machining eliminates the time and expense of ‘blueprinting’ a stock block. With extra-thick cylinder walls, four-bolt main bearing caps, and a competition oiling system, the Little M is the perfect starting point for a powerful and reliable engine for the street or the race track.You can select nodular iron or steel four-bolt main bearing caps, 4.00" or 4.125" cylinder bores, and 350 or 400 main bearings. Don’t waste time on a questionable junkyard block or waste money on machining a “semi-finished” factory casting. The Little M is brand-new, fully machined, and virtually ready to assemble with off-the-shelf small-block components.
