I was fortunate a few months ago to get my hands on a new set of the CompCams "R" hydraulic lifters, which are currently in my head/cam motor. I would have bought another new set but Compcam's doesn't have the lifter anymore. Apparently there supplier went out of business and none are being made. I also don't feel like waiting to take the old motor out to get them as I want to get this other motor 100% completed. Who makes a proven made aftermarket lifter??? I thought that Crane does?? Anyone have experience with them??
