PERFORMANCE BRANDS THAT MAKE A DIFFERENCE

If you were a performance enthusiast looking for cylinder heads prior to 1987, your choices were limited to scrounging through junkyards, going to a dealership for OEM parts, or spending a small fortune on aftermarket aluminum racing heads. There was no in-between option. At this point, noted speed merchant Bill Mitchell and a skilled team of engineering and manufacturing personnel collaborated to develop an affordable cast iron head for the small block Chevrolet that delivered impressive performance gains. Their first offering, the World Products Dart II® (now Sportsman II®) cylinder head, became an instant success and was named Product of the Year in 1988 by Hot Rod Magazine. It produces 30-70 HP over stock heads, and remains the ONLY high performance cast iron small block head to be certified.

PERFORMANCE BRANDS THAT MAKE A DIFFERENCE

Big block Chevrolet enthusiasts were next to benefit from World Products magic? in the form of the highly effective Merlin® line of cylinder heads and engine blocks. Ultimately, the line has expanded to include both aluminum and cast iron blocks and cylinder heads, with complimenting intake manifolds. From street rods and drag cars to off-shore boats and monster trucks, you'll find Merlin power in charge.

The Merlin line has been bolstered by the addition of new Merlin X® aluminum blocks and intake manifolds. These represent a remarkable combination of advanced designs and state-of-the-art manufacturing technology to provide greater levels of performance at affordable prices. Worlds committment to Ford enthusiasts has also increased significantly, thanks to the introduction of the Man O'War® replacement block for 302/351 engines. With the block also came a natural progression to complete engines, with a wide variety of Blue Oval? powerplants now available.

The biggest news, though, is the recent launch of the Warhawk® line of replacement blocks and cylinder heads for GM™s LS1/LS7 and C5R offerings. World's engineering team has collaborated with leading engine builders and racers to create an LS-series block that has many important design features you won't find in the OEM block, plus two cylinder heads; a 12° LS7 model for serious competitors (uses LS7 components) and a 15° high performance replacement for the LS1. Without question, World™s Warhawk products will be setting performance records from coast to coast.

Mopar lovers! Your time has come! In 2008 World introduced the aluminum 426H® and Wedge engine blocks. Numerous enhancements have been made from the original versions that came to market in the 60s. World has also gone back to its roots with the venerable small block Chevy and introduced the Motown® line of cast iron and aluminum blocks and heads. Most recently, World has developed a superior 23° head for GM Vortec (220cc intakes) and a awesome-flowing 235cc model for todays generation of powerful big-inch small blocks. And there are more new developments on the horizon.
