Thoughts on HRC, Summit and Comp Cams evolution lifters

[TexasRoadRunner68]

Any thoughts? I tried to order the Howard Max effort hydraulic roller lifters, but they were backordered. Summit has their rebrand Summit Brand ones in stock for like $640, I believe they use Morel?


I did also find the comp cams evolution lifters. They are supposedly user serviceable and sound like they would be good for higher rpm?

I’m running the Comp Evolution lifters on a Hughes cam, no issues so far. They are fairly quiet, not sure about the higher RPM…I haven’t been much past 6000.
