Lingenfelter designed camshaft profiles to be used with the GM tuned port injection system & the LT1, LT4 fuel injection system. These camshafts were designed to maximize the power potential of your C4 Corvette and work well within the RPM range of the intake manifold. Camshafts will require PCM programming will produce a good idle at 750 RPM. All of the Lingenfelter hydraulic roller cams are produced from a hardened steel core with a unique distributor gear. This eliminates the need for a pecial bronze distributor gear, which must be replaced frequently due to the soft material. Hydraulic roller cams may be used with the stock hydraulic roller lifters after careful inspection for wear.
Some late model applications require a longer drive pin #10214485.
2,600 - 2,800 stall torque converters are recommended.
