Cylinder Block, race prepped Dart Iron Eagle Ford, lightened and machined for 55 mm roller cam bearings

Dart Iron Eagle Sportsman engine blocks are Cobra Automotive’s choice for our vintage road race engines, which are currently making just under 580 horsepower and are being shifted at 8,000 RPM.  These blocks can take the punishment, make the power, and are totally reliable under the most extreme conditions.  Siamesed cylinders with ductile iron sleeves prevent cracking and offer excellent ring seal.  Includes ductile iron main caps, 2 bolt front and rear with 4 bolt interior caps.  The rear main cap uses a standard one piece seal.  Other features include an upgraded oiling system, reinforced blind-tapped head stud bosses, extra thick decks, CNC machine lightening of the entire block and machining for optional 55 mm roller cam bearings.
