We build a lot of circle engines with hydraulic cams that are 135 at the seat and 300 over the nose and we have seen engines come in the shop that have had stock cam bearings in them and they showed a lot wear and tear over the ACL 3349 cam bearings we use in our engines.ImRoyaltyInMyChevy said:
And there about 6 or 7 dollars more then stock cam bearings and much more dependable.
Stock cam bearing are for engines with stock cams and stock springs and most stock springs have only about 80 pounds at the seat.
