    68 L71 Camshaft

    Does anyone know at what time did the camshafts on the big blocks change? Apparently the early big blocks had a grooved rear cam shaft journal for oiling purposes. Was this groove still necessary in the 68's? The solid lifer cam I ordered from Crane Cams for my 68 L71 doesn't have the groove. Any help on this would be appreciated.

    65-maybe 66 used grooved, not needed by '67 or later. Much info in the archives if you do a search.

      Bill,

      You pretty much have it. 65 & 66 have the groove, 67 and later don't.
