Thanks for the heads up.
I thought they were something special by the way everyone makes sure to tell people they are using them.
And I was about to jump on the same wagon and didn't know why.

Thy are fine, they are stock replacement, they might be better than the DOD engine lifters but not LS1.
The LS7 turns a lot of rpm so people assumed the lifter was part of that ignoring the use of titanium and such which had more to do with the rm capabilities.

actually now the entire lineup of LS lifters in every engine is the same one originally used in the LS7, with the exception of a DOD lifter, which obviously is special use for the DOD cylinders.
Standard stuff. Nothing fancy about it.
i highly suggest an aftermarket lifter such as a Morel for any build than an LS7 lifter. too many failures for me to recommend them, although many shops will tell you they 'wont have a problem'

I put a set in my 5.7 about 4 years ago when I did heads and a cam and they never had a problem.
I purchased a new set this past summer for a 408, and at around 50 break in miles, started getting the lifter tick that comes and goes. I could pinpoint it to the driver side, but never could figure out which one was having the problem and they are still sitting in a box, 15 good and 1 bad and no idea which.
If you do ho with a drop in style lifter, get a new set of LS2 trays. They are around $30.
I just said hell with it and went with high rpm linkbars now, no more ticking

Honestly I wouldn't run either. If you want to do a drop in, nothing wrong with them at all, I would run a 4793 (PAC-LFT102-LS) or if link bars a 5206 (PAC-LFT105-LS). I just don't trust OE lifters any more after talking to a few race teams that build LS engines, both road race and drag race. That and seeing how the stocks did on a stock cam with aftermarket rockers on the spintron here.

necessary? I guess nothing is really necessary but IMO its more reliable than a non link bar lifter.
heres a photo for you to decide.
Lunati/Morel vs an LS7
note the massive .750 wheel on the Morel.

i thought so. ive actually seen cams with aggressive enough ramp rate to crack the lower portion of the lifter body unless it has an open design larger 750 wheel like the morel does.
i kid you not. broke them.
