    Dart Big M Big Block Chevy 9.800 Deck 4.600 Bore Steel Billet Caps PN
    31263644
    *** This is a brand new block with a cosmetic issue. This block has a spot of minor porosity on the oil pan face but it's just cosmetic and will seal up 100%. This is a steal price for a brand new billet cap block. I also have others similar to this in 10.200, Small block Little M's & Ford blocks. Ask me if you are looking for something specific. ***
    Dart engineered the Big M to be the strongest, most reliable and easiest to build big block on the market today. The Big M block is fitted with steel billet 4 bolt main caps and is also available in 10.200 deck and bores ranging from 4.250 to 4.600. We also carry the Big M Sportsman line with ductile main caps, check out our ebay store or send us a message.
    Specs
    • Standard 9.800 deck.
    •
    4.600” with siamese 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.
    • 4-bolt main bearing caps steel billet splayed outer bolts for extra strength.
    • 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.
    • Lifter valley head stud bosses prevent blown head gaskets.
