have anyone used the direct lube solid lifters with small hole in the middle of them?your opinions.thanks
I first used a set with a Lunati Solid. I had ordered the Lunati lifters but they were barbell style and I wondered if the narrow middle section would cause a problem with oil pressur
So far, I have only used 2 sets, both were made by Johnson and ordered through Summit. The second set are in my 440/493 with a MP 528 solid. No problems of any kind. They give peace of mind against cam and lifter failures given the rash of problems we have all heard of. I lost 2 Comp Cams in 2006 along with a MP 292/508 in a 360. I've always been careful to follow proper break-in procedures but I was unaware of the reduction of ZDDP.
