Lifter Valley Plate, GM LSX, LS3, LS7 To Replace Factory Cast Part .250 In 6061 Aluminum • Cost-effective alternatives to the factory GM pieces • Does not have the two provisions for knock sensors, which are usually not used in racing applications, as open headers, solid lifter cams and stiff suspensions can false trigger them • Engines that are using a carburetor and distributor also do not need the provisions for the knock sensors, which creates a cleaner installation • Aluminum plate construction weighs less than the factory cast piece and allows specific bungs to be added • Can be used on factory and aftermarket GM LS Series style engine blocks
