Whats the Best Hyd Roller Lifter on the Market? I'm running an aggressive cam and springs with 3/8 push rods in my 383 build and I need a seriously stout lifter that can reliably handle a harsh environment without failure /pump up /ect, so who has the best lifters out? Comp travel limiting lifters any good? Thanks

The GM LS7 lifters have proven to withstand what you're wanting to do and only cost ~$120. The only other lifter that would be more stout is the Cadillac Racing lifters.

Oops, didn't see that, thanks. I have seen the LS7's last even with XER lobes and dual springs though; maybe there's something else going on with his setup?
There aren't too many other hydraulic cams more aggressive than the XER before getting into solid roller material.Jason

if your wanting a top of the line lifter to take the punisment of an agressive valve train look at the Morals, they have a OEM and linkbar type for the LS1. either set runs about 500$ a set but are a quility piece and as stated most of the big names such as lunati, comp, etc.. are rebranding a Moral lifter for use as their high rpm lifter.

Morel hands down.
You have options of a limited travel as well as their their ultimate lifter designed from offshore boat racing.
Yes they are a link bar.

The Ultimate Morel is $750 for the set, features limted travel( .030 )and thicker body walls for sustained higher rpms. This is what I run in my personal car.

Morel. Better material, better tolerancing on the fabrication, better bearings.
The offshore guys run these a lot and an offshore motor is at high RPM high load for extended periods of time. Makes a car look like a cake walk in comparison. Crane used to test their lifters in offshore motor for endurance because of the demands on the lifters.

The Morel lifter is the best I have used in the LS series of engines. I have used them in boosted engines with great results, one of them running 8100rpm and 7 second et's boosted with no problems in the valvetrain.

One more vote for the Morels as in the wheels and axles are also much better. I have yet another set of LS7 lifters with eth wheels coming off on a bracket motor another shop did that was getting into valve float and I have seen this maybe 25 times now on the different OEMs coming apart. The Morels can take a lot more abuse although setup properly the LS7s seem to work great but it's insurance on the Morels mostly for me in abusive situations.
