Johnson 2116 or 2126? I've narrowed down the lifter selection to Johnson 2116's or 2126's.
If you were to pick between these two, which one would you pick and why would you pick them?
Discussions on short travel and/or slow leakdown welcome.
LS3, 427 CI, Ti CSC, Manley severe Flo Pro or Ferrera 6000 valves, Cam and springs TBD.
Please ask any pertinent questions.
Thanks!

First question is what rocker arms are you running and are they adjustable? If they are not adjustable I would stay away from the super short travel ones that need like a 1/8 of a turn preload or whatever. The hassle of getting a bunch of different pushrods is not worth it, the chance of getting it wrong also goes up and if you have shave the heads again you need all new pushrods. They have what I call a medium travel which is .093 of travel and has a more manageable window of .025-.045 preload. Also check the spring load on each lifter style as they do have limits if you are running like 400 pounds open you are OK with either one. If you are worried about rpm capability spend it where it counts like titanium valves or titanium retainers or the new conical or beehive springs. I run the .093 travel ones and rev to 7,000 rpm but what helps is the titanium intake valve that weighs 80 grams and hollow stem exhaust that weighs 85 grams and use the OEM LS7 rockers.

Both the 2116 and the 2126 are available in short travel and non-short travel so that would not be a point on which to choose. Bischoff/BES is going to measure every one anyway and I have zero concerns about them making a mistake. The rockers are YT6667's and are not adjustable but that is not a concern for the same reason.
Titanium intake valves would be nice but may not be the best choice with a CSC. I am leaning toward robustness so hollow stems are probably not the choice there either.
Not sure you would need titanium intake valves if you are only spinning to 7,000.

Here is an answer:
Jim,
There is more.....the less expensive 2116 linked above doesn't have the axle oiling feature. And its a "limited travel" lifter that has more travel than the more expensive short travel (.093 vs .058). Both are high quality.....short travels require more precise pushrod lengths and I normally recommend my clients check every cylinder with the short travel. FWIW, stock lifters can have plunger travel approaching .200, so .093 is alot less even in the limited travel option.
Axle oiling refers to the wheel actually getting pressurized oil to it from the lifter galley as opposed to having to rely on "splash oiling" from the crank which can be very little at idle and low RPM. It adds big time to the reliability factor.
PM me for more info, pricing, etc., and I can help guide you into which unit might be best for your application etc. assuming your in the market for lifters at the moment. The right lifter is worth serious power in an engine with more spring pressure, cam ramp intensity, and RPM and is often overlooked in budget and non budget builds for that matter.
