FWIW… I think a bushed lifter has its place with big cams on the street or racing. But on the street with a mild roller cam the needle bearing lifter will out last a bushed lifter by a lot. The...

I was recalling the Evolution lifters for an LS that have .150” travel. I did not realize Evolutions for a Pontiac have a little less travel.

I think Tom S is looking up the instructions he used...

Oops, thanks, I should have looked it up. :).
.125” is still considered a standard travel

Evolutions also have pin oiling.

The HLJ site is tough to navigate and the searches often do not work. I recall HLJ saying short travels have a 70% reduction in life.

The “S” on the end of the part number on a HLJ means “slow”, they are full travel.

I am curious Larry if your 327 has the slows instead of shorts? Last I recall HLJ reps did not make short...

Evolutions should be able to handle that. They can likely handle more aggressive profiles like an XFI at those pressures, but I think something like an XFI might be getting on the edge of what they...

The S means it is ground with a smaller diameter small block journal, that is what I thought it might be. It will likely make quite a bit of extra sowing machine noise with ST lifters, smaller base...

I think the PR lifters would have likely held the 200 lbs of seat pressure and 420 at max lift, the evolutions have a smaller diameter plunger, that apparently created issues with too high bleed...

That much seat pressure usually requires short travels. If you have to run much over 160 it is usually time to run short travels.

Does anyone know what became of the gentleman (last fall or early spring) that had his engine on the dyno and was having trouble with the Evolution lifters? Did he get it figured out?

The evolution are standard travel (.150”). I would think they would work fine with that cam, but I have not used any yet. That UD profile family isn’t all that picky about lifters and bleed rates. ...
