World Products’ revised Motown LS “hybrid” block provides engine builders the opportunity to combine high-flowing, efficient cylinder head and intake systems for General Motors “Gen III” LS-series applications with the superior bottom-end and lower component costs of the venerable “Gen I” small-block Chevy. Designed to accommodate OEM and aftermarket LS-Series cylinder heads, World’s Motown LS block provides a “best of both worlds” combination, eliminating the drawbacks of the Y-block design used in the LS. The Motown LS blocks also have priority main oiling and expanded water jackets for better cooling. Standard small-block Chevy motor mounts and bellhousing pattern are utilized, making this an easy bolt-in path to serious power. Call 877/630-6651 or visit www.worldcastings.com for more info.

Getting A Grip
PowerTrain Technology recently announced its 5.5-inch and 7.25-inch Power-V Racing Clutches are now available with a new and improved sintered bronze metallic clutch friction material. PTT’s proprietary new friction material has better clutch engagement characteristics, and a positive feel. The micro-finished friction surface requires no bedding-in when first installed, and increases clutch life by reducing wear on mating parts. The sintered bronze metallic material has been custom blended for use with a variety of import and domestic automotive circle track, road racing, and rally racing applications. Standard material thicknesses of 0.105-inch, 0.200-inch, and 0.250-inch are available.

Ever wonder what happens to many race car components when the chassis is continually bottomed out? Damage—that’s what! Allstar Performance’s engine mount spacers are made from a unique material that will not let the engine vibrate under normal conditions, yet they “give” a little during bottoming out, easing life a bit on engine and driveline components. The 1/4-inch-thick spacers are 11/2-inch OD and have a 1/2-inch hole. They are sold in a package of two. For more info, contact Allstar Performance at 269/463-8000 or visit www.allstarperformance.com.
