Small Block Chevy Replacement Blocks with Major Muscle

World Products Motown II Small Block Chevy Cast Iron Blocks are entirely manufactured to QS-9000 specs using only two fixturing operations (no tolerance stacking like factory blocks made on an assembly line). Compared to OE models, World’s Motown II engine blocks contain thicker cylinder walls, and the expanded water jackets help improve cooling. Each engine block includes one-inch thicker bulkheads (to provide ample support of the front and rear mains), bosses for front-feed oil systems, and rear dry-sump scavenging. Solid pan rails (standard width design) ensure proper sealing, and stock-type oil pans can be used.
