Chevy Blocks
Dart blocks for small and big block Chevy engines are designed from the ground up for hard core racing, all the weaknesses of the factory castings have been adressed. Dart blocks are brand-new, fully machined, and virtually ready to assemble with off-the-shelf components. Don’t waste time on a questionable junkyard block or waste money on machining a “semi-finished” factory casting. 

Chevy Small Blocks
Dart's iron and aluminum blocks for small-block Chevy are loaded with features you won't find in any factory casting. We've eliminated the compromises found in production blocks with extra-thick cylinder walls and decks, 4-bolt main bearing caps, and a competition oiling system. Our precision CNC machining and strict quality control measures mean you get optimum out of the box performance without requiring costly machining operations after purchase.

The Little M Sportsman block is the affordable alternative for sportsman racers and serious street performance. Eliminate the time and expense of ‘blueprinting’ a stock block. The Sportsman is brand-new, fully machined, and virtually ready to assemble with off-the-shelf small-block components. With extra-thick cylinder walls, ductile iron main bearing caps (4-bolt on the center three and 2-bolt on the ends), and a competition oiling system, the Little M Sportsman 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. Don’t waste time on a questionable junkyard block or waste money on machining a “semi-finished” factory casting.
