Gen III/IV Small Block Engines - Big Displacement Gen III/IV Engines

If an all-aluminum Gen IV engine has you captivated, SLP and Scoggin-Dickey Parts Center (SDPC) build 402ci or 416ci alloy engines. SDPC combines an L92 aluminum block with a 4.067-inch bore and a 4.00-inch stroke Eagle crank, along with Scat H-beam 6.125-inch rods to produce this lightweight package. If that seems tame, the company also offers El Toro Grande (The Big Bull), a 440ci LS7 block motor with a 4.100-inch stroke crank pushing 4.127-inch-wide pistons. The only thing bigger is World Products' Warhawk block; this aftermarket aluminum block can pump the bore up to a wide 4.125 inches. When you combine that with a 4.00-inch stroke crank, it equals a Rat-like 454 ci.
