my lifter bores and lifters look fine, never spread any forks that was part of what I seen happen with morels and other brands if there are issues...never happened to me personally..guys you gotta get off this lifter bore thing with me... if they were the issue I would have other issues and my cams would not look exactly like dozens of others...
Agree. Wonder if there is any unusual wear patterns in the lifter bores. Have they been cked since tear down? Something is obviously out of whack but again what about the other similar failures... Blocks being used again? I missed the fork spreading post. That's a whole new issue but again goes back to valvetrain stability.

Did cam motion ever get back to you on the cams?

My comment about the lifters spreading forks, was in response to the lifter sales talk, about why a .700 wheel with a shrouded body is better than a .750 wheel fork style lifter. If the design can work fine in applications running rocker ratios in excess of 2.0, top fuel engines, nascar, pro stock, etc, I think it should be ok in a 6k rpm hydraulic combo.

So now the johnsons suck even though many have he success there also?
If crower, Isky and Teague are using them for the last few years I can't say they are suck lifters, many guys I know use morel also with no issues as we have seen guys state earlier in threads, not trying to get into a pissing match with a friend or anyone here but now it's a hate Johnson post with no proof of anything
