PRODUCT FOCUS: Engine Building Components Power. Reliability. Durability. Efficiency. Engine building components are at the heart of what aftermarket professionals look to create every day. From blocks, cranks and cams to heads, manifolds and pumps, the infinite combinations are what excite engine builders and drive their creativity. From the bottom to the top end and everything in between, the following are some of the latest engine building components available to the performance and racing aftermarket. Take a look to see which ones might get your customers' hearts racing. New Engine Block Dart Machinery, Troy, Mich., introduces its Little M 305 5-Liter Engine Block, offering a standard bore of 3.750 inches and a maximum bore of 3.800 inches. Created as a direct replacement for GM's 305 small-block, which was used extensively in muscle cars, passenger cars, pickups and boats from the mid-1970s to the mid-'90s, the block also satisfies the demands of RACESAVER, the prominent Sprint car nationwide racing series. Produced in premium cast iron alloy, the Little M 305 engine block offers complete water flow around all cylinders. 50-Ton Ironworker Scotchman Industries Inc., Philip, S.D., introduces the 50514-CM 50-Ton Ironworker. The American-made, fivestation ironworker features a 50-ton punch station with a keyed punch ram, 4-inch angle shear, 14-inch flat bar shear and built-in rectangle notcher. A fifth station next to the angle shear allows an optional pipe notcher to be mounted without removing the angle shear. Pontiac Aluminum Stud Girdles Conical Valve Springs COMP Cams, Memphis, Tenn., presents its new line of Conical Valve Springs that utilize round wire and feature a diameter-driven and progressive pitch-driven natural frequency. The design increases the valve train rpm limit while reducing resonance concerns and dynamic spring oscillations for longer spring life and the ability to run more aggressive camshafts. The constantly decreasing diameter of the spring from bottom to top reduces active mass, thereby decreasing applied dynamic valve train forces. 14 n Performance & Hotrod Business PHBFEB.indd 14 n PRW Industries Inc., Placentia, Calif., presents its billet aluminum stud girdles specifically designed for 1959-'79 Pontiac 326-455 engines. The stud girdles are made from 6061T6 aluminum extrusions and manufactured specifically to fit Edelbrock heads. Each PRW stud girdle was designed to reduce rocker stud flex in order to retain critical valve lash adjustments, providing more accurate valve lift and timing. Each girdle is relieved at the factory to accommodate crankcase components. February 2014 1/3/14 11:53 AM
