Re: 428CJ Stock Class Valve Lift .527 ?
Its applicable to all 428 cobra jet engines. I had built a brand new 428 for my Torino over 20 years ago and this rule changed allowing the .527 camshaft. The addition of parts at that time in A-D cars was out of control. It was by no means brand specific. There have been many battles to take parts back but have only been successful taking parts from mopars.
