World Merlin Pro Iron Big Block Chevy Blocks

Here's the block that's been the foundation of many a Pro Stock, Pro Mod, Top Dragster, tractor pull and offshore marine powerplant over the years. It's engineered to handle 2,000-plus horsepower without strain, and has compiled an enviable record of total dependability. Important features contributing to the Merlin's reliability include a siamesed cylinder wall design, solid front and rear bulkheads, extra webbing throughout, reinforced lifter bores and valley head stud bosses.
