Engine Blocks

Dart Big "M" Block

  The DART cast-iron Big ‘M’ Big Block is a no-compromise design that solves the problems that have plagued Big Block Chevy engine builders for years. DART has redesigned the lubrication system to create a true “priority main” system that oils all of the main bearings before the lifters to increase reliability. The stepped main oil gallery increases the flow of oil to the crank at high rpm and the front oil crossover eliminates internal oil leaks around the distributor shaft. This results in more oil at the bearings and pushrods where it’s needed, and less power-robbing crankcase windage.

  The BBC is prone to head gasket failure in the long spans between head bolts. DART has solved this problem by adding two head stud bosses on both sides of the lifter valley to take the place of the “missing” head bolts.

  The DART Big ‘M’ is the strongest, most reliable and easiest to build BBC on the market.  That is why Remer-Morrison sells and equips every Super Series BBC with a DART Big "M" block.

Dart Little "M" Block 

  The new cast-iron Dart Little "M" block uses standard small-block components - then adds features you can't get in any production block.  With extra-thick cylinder walls, four-bolt main 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 track.

  Don't waste time on a questionable junkyard block or waste money machining a "semi-finished" factory casting.  You can select from 4.000" or 4.125" cylinder bores and 350 or 400 main bearings.  These brand-new, fully machined blocks are 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!
