The top 2 selling lifters are Evolutions from Compcams, and the Johnson 21160PR (which also go by Isky 9077hyrt and Crower has a part number also) Isky’s online catelog is hard very to sort thru, they never seem to have all their inventory listed. You have to call them to order something. It has always been like that. Gaterman’s the same way, you have to call them.
I have suggested Johnson lifters before, I am not afraid of them. I wish Isky would sell the HPx for a Pontiac. Quite a few guys choose Johnson over the Comps because the comps have more offshore parts in them, not everyone loves Compcams. I have Johnson mechanical rollers in one engine.
I actually have Hylift Johnson hydrualic rollers on the shelf, which is also an American made lifter.I have not mentioned them because I feel plunger valving is superior on the Johnson PR (or Isky 9077) for the cam you have.

Do you like the Evolutions over the johnson 21160pr? I see they have another one that has shorter travel. ST21160PR. .030 total travel? Whats your thoughts on that one?
