World Products Motown Race Engine Blocks

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.

Chevrolet Performance Bowtie Big Block Chevy Cast Iron Engine Blocks

Chevrolet Performance Bowtie big block Chevy cast iron engine blocks are CNC-machined. The race-prepared blocks feature blind head and accessory mounting bolt holes, a deck configuration that enables the use of any big block Chevy cylinder head—and cylinder bores that may be safely bored to a 4.600 in. maximum diameter, while maintaining a .250 in. minimum cylinder wall thickness. These engine blocks differ from the production-machined Bowtie versions in certain areas; they start from raw castings and are not "conversions." They also use a rear seal adapter to convert the Gen V/VI one-piece rear main seal to a Mark IV type 2-piece seal that facilitates the use of a widely available Mark IV style crankshaft. The intermediate caps also feature 16 splayed outer bolts, which anchor the caps into the strongest section of the blocks and prevent bearing cap movement under high loads. The main oil gallery on these blocks is relocated and enlarged to a 9/16 in. diameter to allow increased oil flow through the block. These Bowtie blocks have inner head bolt bosses, which allow for better retention of the cylinder heads in high-horsepower applications when the cylinder heads "lift" from the blocks due to high cylinder pressures. Order the style and deck height preferred for your application.
