Was looking at the article Andy F did on the 470/trick flow combo, where he is running AMC 848 lifters in order to have pin and pushrod oiling. But, comp cams has a new part number of 861 for the AMC lifters. Will these still work in an unbushed 440 block without problems? If so they are a cheaper alternative to running other Chrysler specific lifters with the pin oiling and pushrod oiling.

Anyone with experience on this?
