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

The Little M gives you the choices you want in a production-type block.  You can select nodular iron or steel four-bolt main bearing caps, .400" or 4.125" cylinder bores, and 350 or 400 main bearings.  Build it your way with Dart!

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.  You'll make more power and save money in the long run with a strong, reliable Dart Little M block!
