EDM lifters were made and designed to be used in BB Chevy motors due to their poor lubrication of the lifters and cam lobes and tight lifter to lifter bore clearances: work: scope
Every BB Mopar I've check the lifter bores on have a BUNCH of lifter to lifter bore clearances scope
I've primed more than one BB,SB and Gen 2 426 C.I. hemi motors with the lifter gallery expose, they flat push a lot of oil out around the lifters under pressure scope
My message is we don't need EDM lifters, use a good oil high in Zinc content instead to make the cam and lifters live up twocents [/quote]

The Chrysler service manuals show a lifter bore size of 0.9050" to 0.9058". I believe the aftermarket has sized their lifters for a slightly smaller size, resulting in the lifter bore flooding. I talked to Billy Godbold at CC about it. He said he changed the lifter size when he first got to Comp, but they had complaints from the Brand X racers and they changed it back.
