Excellent racing, marine performance upgrade or stock replacement block. Street performance, sportsman racing, wet sump.

Dart’s Iron Eagle Sportsman block is the affordable alternative for sportsman racers and serious street performance.

The Sportsman block shares most of the Iron Eagle’s best features, but saves you money. Dart blocks are cast from premium high strength iron with extra thick cylinder walls and decks. Main bearing caps are 4-bolt on the center three and 2-bolt on the ends to simplify oil pan fitment.
  • Siamesed cylinders: Standard 4.00” or 4.125” cylinders can be safely bored to 4.185” diameter, extra thick walls prevent cracking and produce excellent ring seal.Steel 4-bolt main bearing caps are standard. Three center caps have splayed outer bolts for maximum strength; rear cap uses standard one piece seal. Sportsman blocks use 4-bolt centers and 2-bolt end caps.
  • Upgraded oiling system has been completely redesigned with a low restriction priority main oiling system with rear external oil pump feed.
  • Scalloped water jackets increase coolant fl ow around cylinder barrels to prevent detonation, extend engine life and produce consistent cylinder temperatures.
  • Stock components make Dart blocks a direct replacement for most production small blocks. Provisions for stock motor mounts, accessory drives, smog pumps, starter brackets, oil pans and pumps.
  • Reinforced head bolt bosses are blind to prevent leaks and produce more accurate torque readings. Extra thick decks prevent head gasket leaks.
