Post by: FC427 on December 21, 2007, 04:20:08 PM
Need Help with rocker settings on a Grey with a 40 / 80 cam the motor is in a car and I am just trying to help out another member by setting his rockers so he can get to Summer Nat's no cam card came with the motor I realise that all cam grinders use different lash but if I get a couple of answers it will be a starting point I have not measured the lift or anything else so I am blind at this stage......FC427........
