Our LT Superdeck Short Block is based on our legendary LS Superdeck block system assembled with a bullet proof rotating assembly. This is ta reliable short block for forced induction applications that require stronger cylinder walls. The truss design of the ERL SUPERDECK adds unmatched strength and stability to the bock and deck surface. This truss allows the load to be shared across the deck surface minimizing deck deflection. The ERL sleeves are significantly longer avoiding piston rock at BDC. The block receives ERL Doweled Billet main caps, made in house. These caps are solid doweled which helps prevent any sort of cap walk.  These short blocks are capable of handling over 1500HP with additional options.
