    Small Block Chevy Replacements with Major Muscle
    Here's an answer to the needs of performance enthusiasts for an alternative to searching through junkyards and swap meets for now-scarce factory 4-bolt main blocks, or puchasing an aftermarket block that requires special components. World's Motown block is 100% compatible. One of the more noticeable differences between the World Motown and OE Chevy blocks are the bulges at each cylinder. That's because the Motown has thicker cylinder walls, and the water jackets have been expanded to provide required cooling. Other physical differences include creating 1'' thicker bulkheads to provide ample support of the front and rear mains and the addition of special bosses for front-feed oil systems and rear dry sump scavenging. Solid pan rails are used to ensure proper sealing. Crankshafts with strokes up to 4.000'' can be used without clearancing the block. Stock-type oil pans can be used (no special wide rail designs). Most importantly, the block is manufactured in its entirety to QS-9000 specs using only two fixturing operations (there's no tolerance stacking as with factory blocks made on an assembly line).SPECIFICATIONS
