Speed and Flow

Many of America’s most successful companies can trace their roots to basements, tool sheds and spare bedrooms. Like Hewlett-Packard, Boeing, and Apple Computer, Dart Machinery began in humble surroundings. Richard Maskin founded Dart in 1981 in a two-car garage in Oak Park, Michigan. In the years since Maskin started his business with a desk and a telephone, Dart has become the proven leader in aftermarket cylinder heads, intake manifolds and engine blocks.

Dart is committed to producing the best engine components available. All development, machining and assembly are done at Dart’s own facilities in order to maintain the highest standards of quality. State of the art CNC machining centers, a computer controlled dynamometer and the proprietary “Speed Flow” technology / wet flow bench are among the assets which contribute to “the Dart advantage”.

Blocks

LS NEXT ALUMINUM FULL SKIRT

Designed from a clean slate approach the LS Next Aluminum block has addressed the shortcomings of the LS platform and is the ideal candidate for hot rodders, drag racers, circle track competitors, off-roaders, and high performance marine enthusiasts.

 

 

BIG M RACE SERIES

We raised the camshaft and spread the oil pan rails to provide extra clearance for stroker cranks. The versatile Iron Eagle block is the perfect starting point for a big cubic inch small block project.

Dart’s Race Series Aluminum big block is based on the Chevrolet big block V8 design, with added features like increased deck height and a raised cam location.

The camshaft is raised .400″ above the stock location to increase clearance for the connecting rods and crankshaft counterweights. The main oil gallery is located alongside the camshaft tunnel to eliminate interference with the crank assembly.

Advanced engineering makes Dart Aluminum big blocks the choice for serious competition. 

RACE SERIES SBF

The Dart Aluminum small block is light, strong, and affordable. With displacements up to 450 cubic inches, the Dart Aluminum block is ideal for sprint cars, modifies, late model stock cars, dragsters, and unlimited competition classes.

With pressed-in dry sleeves, upgraded oiling and steel 4-bolt main caps, Dart’s Aluminum blocks have the features that Ford racers need to build powerful and reliable engines.

 

RACE SERIES HONDA B-SERIES

Dart offers the Honda block in two versions that replace B18 and B20 castings. Both are built to withstand the extreme cylinder pressures created by turbochargers and nitrous oxide injection.

 

We increased wall thickness in all critical areas and we beefed up the bottom end with steel main bearing caps. Best of all, Dart blocks are compatible with production Honda cylinder heads, internal components and accessories.

HEADS

RACE SERIES LS 10° 368CC CNC

By utilizing conventional style main caps and oil pans with LS rotating assemblies and related components, Dart has addressed the windage and oil control problems which result from the factory LS engine’s separated crankcase bays.

No other areas of racing engine development hold as much potential for increased performance as the cylinder head and its related components. Dart continues its revolutionary approach to perfection and power in this area by the recent release of their all new NMCA Pro Stock cylinder head.

Recommended for maximum competition LS engines with 4.125” bore or larger. Drag race, maximum competition, naturally aspirated, heavy nitrous or forced induction applications.

Dart’s New Race Series 10° LS cylinder head is the ultimate choice for maximum competition. Designed with raised Pro Stock oval ports, canted valves and highly efficient wedge style combustion chambers, the Race Series 10° LS is a radical departure from traditional LS heads in one other area. The intake and exhaust valve locations for each cylinder have been reversed. This feature has been the standard for maximum power wedge engines for decades.

The huge flow resulting from the 10° valve angle, splayed valve layout, reversed symmetrical intake ports, and highly efficient combustion chambers deliver maximum power!

It is recommended that you contact a Dart technical representative before placing an order for this item. Detailed information about your planned engine build will help to ensure that you choose the right configuration for your motor and that any special parts are taken into consideration.
