Product Description

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 reliable and affordable engines.


  • Premium alloy: Dart aluminum blocks are cast from virgin 355-T61 aerospace alloy for superior strength and integrity.
  • Siamesed cylinders: Standard 4.000” or 4.125” cylinders can be safely bored to 4.165” diameter. Ductile iron sleeves and extra thick walls prevent cracking and produce excellent ring seal.
  • Scalloped outer water jacket walls improve coolant flow around the cylinder barrels to prevent detonation, extend engine life and produce consistent cylinder temperatures.
  • 4 bolt billet steel main caps. Three center caps have splayed outer bolts for extra strength; rear cap uses standard one piece seal.
  • Two main bearing diameters 302 (2.249”) or 351C (2.749”) allow choice of small or large journal camshaft.
  • Provisions for stock motor mounts, accessory drives, smog pumps, starter brackets, oil pans and pumps.
  • Upgraded oiling system has a complete stock type system plus a low restriction priority main oiling system with front and rear external oil pump feeds.
  • Dual crossovers allow oil flow to be metered with restrictors for roller lifter cams and/or rocker roller arms to reduce oil flow and windage.
  • Reinforced head bolt bosses are blind tapped to prevent leaks and produce accurate torque readings. Extra thick decks prevent head gasket leaks.
  • Includes coated cam bearings, freeze plugs and dowels.
  • Machined with front and rear external oil feed, crossover and restrictor provision.
  • Dart blocks are available fully finish prepped.
