BBC Dart Big M Sportsman Block 4.250 Bore 9.800 Deck

Brand New Dart Big M Sportsman engine block for a Big Block Chevrolet application. 4.250" Bore Size, 9.800" Standard Deck Height, Ductile Iron Main Caps. Sportsman blocks give you the versatility to build a wide variety of engine combinations. A true priority main oiling system oils the main bearings before the lifters for extra reliability. This block is not a factory blem/2nd. It is a first quality block, absolutely free of defects. 

Dart Big M Engine Block Specs:

  • Dart Part #31273344
  • Siamesed extra thick cylinder walls to resist cracking and improve ring seal (minimum .300" thick with 4.625" bore)
  • Uses +.300" tall Gen VI style lifters. Modification for Gen IV style available.
  • Scalloped outer water jacket walls improve coolant flow around the cylinder barrels to equalize temperatures.
  • 2 bolt front and rear and 4 bolt interior ductile iron main caps 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. Our stepped main oil gallery (9/16" to 1/2" to 7/16") increases the flow of oil to the crank at high rpm, and our front oil crossover eliminates internal oil leaks around the distributor shaft.
  • Oil filter pad is drilled and tapped for an external oil pump.
  • Lifter valley head stud bosses prevent blown head gaskets.
  • Rear main cap uses standard oil pump and two piece seal - no adapter required!
  • Mechanical fuel pump boss, clutch linkage mounts, and side and front motor mounts simplify installation in any chassis.
  • Dual oil pan bolt patterns fit standard and notched oil pans.
  • Coated cam bearings, freeze plugs and dowels are NOT included but are available for sale on our ebay store.
  • Blocks are shipped from Dart rough bored and will need to be final honed to your pistons.

Please see our Ebay Store for Dart cylinder heads, intake manifolds and complete top half packages.
