  • $ 11,250

LS Superdeck I Short Block combines our legendary Superdeck I block with a bullet proof rotating assembly of up to 454 CI. This is the perfect short block for forced induction, nitrous and high performance N/A racing engines. The truss design of the ERL SUPERDECK I adds unmatched strength and stability to the bock and deck surface. The truss design (shown in the pictures above) involves connecting each pair of head bolts through an aluminum truss. This truss allows the load to be shared across the deck surface minimizing deck deflection. The ERL sleeves are significantly longer and thicker than stock sleeves, this allows for up to a 4.125” stroke and a 4.185” bore. The 6 bolt Superdeck I Short blocks are available with the ultimate in rotating parts with Callies Ultra Billet Rods, Callies Crankshaft and Wiseco or Ross pistons. These short blocks are capable of producing up to 1500HP. ARP main stud kit included and installed.
