World's Motown blocks are without a doubt the most feature-laden, engine builder friendly, cast iron blocks on the market. And because of their superior temperature control and rock-solid stability, experts claim they're worth up to 20 hp more than other blocks on the market! At first glance, one of the more noticeable differences between the World Motown and OEM Chevy blocks are the 'bulges' at each cylinder. That's because the Motowns have thicker cylinder walls, and the water jackets have been expanded to provide required cooling. Order the model and options preferred for your application. Important features are as follows: * Made from high-density cast iron * 9.025 in. deck height with .600 in. minimum thickness * Dry sump valley scavenge lines drilled * Clearanced for 4.000 in. stroker crankshafts (H-beam steel rods) * Integral mounts for spin-oil filter * Dry sump systems can feed from front or rear of block * Available with 4-bolt nodular or splayed billet caps * Can be bored to 4.200 inch maximum * Water jackets expanded for better cooling * Standard Chevy cam location and cam bearings * OEM starter, fuel pump, and engine mounts (dual) * Blind tapped head bolt holes for extra integrity * 100 percent compatible with OEM parts * Indexed lifter bores (can use standard-height lifters) * Main caps are located by dowels (not OEM outside register) * Weight: Approximately 190 lbs.
