What pics are you looking at? the new lifter extend deep over the rollers and eliminate the bleed off with all other lifters.

Judging from the pics, it appears that the length of the lifter skirt is still about the same as the old Crane or the new Comp Cams lifters. It does not fully shroud the roller wheel. So wouldn't the Johnson lifters still have the same "oil bleed-off" problem as the others do with cams approaching .700 valve lift. Would still have to bush the lifter bores to avoid dumping oil pressure at max lift. |

I was at the AMO meet in Michigan, They had a rep there and looks like the real deal. Problem solved. Jonson lifters contact Joe Lewis product manager 1-800-860-4233 Taylor MI or Email jlewis 5226 @aol.com, Joe is a really nice guy. He spent a lot of time talking to me and others and explaining the correction and the benefits of Johnson lifters over other brands and I agree they do like a very high Quality piece. A little bit more in cost but problem appears to be solved.

SKeown, Where can we get some info (pics/prices/dimensions, etc) on these Johnson lifters? I couldn't find much on the net.

I understand that Johnson Lifter Co has completed their AMC solid & hydraulic roller lifters and they are availiable now for sale. The pictures I've seen look good and have addressed the issue everyone is concerned about.
