new lazy lifter....

Actually, quite the contrary.
The tightest tolerances in the entire engine.
Which is why there are often problems with them....... since it’s easier to be outside the tolerances when the range of tolerance is so small.

For quiet operation, I’ve seen the best results over the last several years by not using really fast lobe designs, and using the Hylift Johnson/Topline slow bleed lifters(“s” suffix.....A-2011S for the SB Mopar).

Exactly correct. Even with the best hydraulics you can get, a modern, fast lobe just makes the internals unhappy.

I know I've posted this before but I'll do it again just because someone else may read it that hasn't seen it before.

Fast lobes is why I stopped using hydraulic roller lifters. The customer wants all the power of a roller lobe but wants the dead quiet of his low output, daily driver turd. It just doesn't happen.

So we started using hydraulic roller lobes and putting solid roller lifters on them. You lash them at .0015-.0020 cold and run it. You can't hear the lifters when the hood is shut, they run so much better that it's not funny.

Sometimes you can't have both. You esprit her need to use a slower lobe and live with that, or just put a solid in it and live with that.

I know if I had one or two lifters ticking it would drive me wild. I'd personally rather have the solid.
