I'm also surprised that this is not a more common subject especially since mopar delivered some blocks with lifter bores of .912. I bought a block that unknowingly to me did have all 16 lifter bores at .912. It took me some time to determine where my oil pressure was going after the engine warmed up. I finally figured it out and was lucky to buy 16 of the last 52 lifters in mopar inventory. Since it cost so much to bush lifters I will definitely try a resurface on the lifters I have. If there were other reasonably priced options I would definitely consider them. I'm lucky that the block is currently sitting awaiting determination on what I want to do with it. Anyone had this problem before?
