I seem to remember one of the Mopar tech line guys telling me many years ago that Mopar had switch vendors, cam grinders on all their cams and the one I was calling on complaining about not having the advertised lift was due to the vendors not grinding them correctly.
He also said later that Mopar had two different specs. throughout the life of the "590" grind, LSA being different as well as on lobe lift
Any one else seen or heard of this?
OP, I use to use a Isky grind, .616/.590 split duration cam for BB Mopars ground on a 104 LSA, that was similar to the original Mopar "590 grind.
that cam worked very well installed from straight, 104 ILC, up to being advanced to 99 BTDC on the ILC
