The Little M is designed from the ground up as a true high performance block which can be used with standard off-the shelf small block components. It is cast from premium high-strength iron and beefed up in all the critical areas. With a standard deck height, extra-thick cylinder walls, 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 4.00" or 4.125" cylinder bores, and 350 or 400 main bearings. Front and rear external oil feed, crossover and restrictor provision. Includes coated cam bearings, freeze plugs and dowels.

Dart blocks are optionally available fully finish prepped. If you choose to order your block this way you can specify a final lifter spec and a final hone spec. Your block will be finish machined to your specs, final prepped and washed, pipe plugs and freeze plugs will be installed, then it will be bagged and boxed. Your block will arrive finished and ready to use!
