i hate it when i get wrong parts......
A couple of years ago I got a Comp Big Block cam/lifter kit from Summit. Lifters were sloppy in the bore so I measured them...Ford lifters (Mopar part number on the box). Summit sent out another set of Comp lifters. Same thing, Ford diameter. They exchanged them for a set of Crane lifters that I swear came off the same assembly line, except that they were Mopar lifters. The box was the same exact dimensions and construction. The printed label was the same layout with the same fonts...
