the older blocks 65to67 did not have the 360 groove in the#5 cam housing bore of the block so oil from mains would not oil the lifters with out the cam groove or the right cam bearings. new blocks do not need this done to the cam is it has the 360 groove in the rear cam housing bore older sbc are the same way
