World Products Motown Race Engine Blocks

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.
