Going back to solid rollers
Yeh I'm another victim of noisy hydraulic roller lifters.I thought the new version of the lunati lifters would be the end all cure all of the noise.Im willing to try a different lash setting technique that was recommended on this site,and that was to bottom plunger out then lash up 1/2 to 1 turn.Any input on this procedure is welcomed.

Those short travel Johnson lifters have been the best ones I've tried so far. I also like and run the Crower Solid lifters for years with no issues.

Morel makes Lunati.When I did my 383 engine we had one pair that was bad,they got exchanged and all were good.My next engine will use the new Coms with exchangeable cartridge.Tom

I just installed the new Comps in a motor 2 weeks ago and they adjusted well and make zero noise.

Lunatis work fine w a small trough ground into the body with a burr bit should you have to do this no. However I believe it will quiet your
Lifters as it has done a Few sets I have dealt with and others. There is a thread buried in this section that shows this being successful many years ago I do not Recall who the gentleman was that “pioneered” this morel fix And to be fair I had to similarly modify some Crower solid rollers for My ia1 almost 20 years ago In each instance the lifter gets more Oil to the top end and Quiets down considerably in my humble Opinion

BAM solid roller lifters with DLC option .
Good enough for big power Drag Week guys. Have not heard a bad thing about them. They are based on a high end Crane lifter that is not available anymore. |

or is it that a part of that feed hole is in the full diameter body

Yes it is probably the better option. it’s just more involved (motor apart) and it’s forever or atleast until
You bush the lifter bores The notch made a huge improvement in quieting down these lifters and getting oil to the springs at idle The set that I did that has the most miles on them we bought used w a new Howard’s hr, and it probably has about 1500-2000 miles since leaving my garage not a huge sample but a nice start The second set I did on my Motor probably only 300 miles so jury still Out these are on an xr288

I’ve got a noisy pair setting on my bench that I’ve been messing with. I can’t seem to get the parts out of the inside because the link bar rivet is in the way. Am I missing anything? Thanks Murf |
