Dart Big M Cast Iron Block - 10.200" DeckĀ 

Dart Big M Cast Iron Block - 10.200" Deck

  • Scalloped outer water jacket walls improve coolant flow around the cylinder barrels to equalize temperatures.

  • Standard 9.800" and extra-tall 10.200" deck heights available for stroker engines.
  • Four-bolt main bearing caps in steel or ductile iron have splayed outer bolts for extra strength.
  • Crankshaft tunnel has clearance for a 4.500" stroke crank with steel rods without grinding.
  • True "priority main" oil system lubricates the main bearings before the lifters.
  • Oil filter pad is drilled and tapped for an external oil pump.
