Return to Parts List Category : W2- Wedge World Tech HUG WEDGE WORLD TECH A16 TECH INFO ABOUT RATTLING VALVE TRAIN $0.00  WEDGE WORLD TECH From Hughes Engines  Dedicated to bringing news And truth to wonderful World of Mopar wedge engines   Issue #16 Rattling rockers, pushrods, or lifters “My rockers (pushrods or lifters) are rattling since I put in a new higher lift cam.” Cams with higher lift DO NOT HAVE A HIGHER LIFT. They have a SMALLER BACE CIRCLE and since the lift is the difference between the base circle and the top of the lobe the lifter drops down in its bore. The lower lifter position means you now have greater (a lot greater) clearance in the valve train (that means noise to the chatter). This extra clearance must be made up with longer or adjustable pushrods, adjustable rockers, or both. We usually have both available. Pick up the phone and give us a call!!
