Anyone run more than .060" preload on Morel 5206 lifters?
Purely out of curiosity.
I see that .060" seems to be the suggested preload, where Morel suggests .045-.050" on aluminum head and aluminum block combos, and less on other setups (iron block, aluminum/iron heads, etc.).
I can do .060" but was wondering if there are setups out there with more.
I've read anywhere from .122 to .14x" as the max travel on these lifters.
Any opinions/advice/experience is appreciated.... I'm setting up an ERL LS3 434ci with LPE-ported LS7 heads and GT19 cam (with LPE's ferrea spring/retainer kit for said cam).
Thanks.

.122 to .144 may be the max travel on thes lifters but you don't want to bottom the lifter out. This is why it's hydraulic. You want to set the pushrod depth about midway.So .050 to .060 is fine.

I was just wondering if anyone ran more than .060" (more like .070-.080") with the morel lifters (5206 link bar lifters, specifically) ...I know you don't want to bottom the lifter.
Thanks.

I'll see how the current preload setup works for my combo and go from there, I suppose.

I'm just over 2k miles into this new bullet. I started with Comp Cams' break-in oil (10w30) and ran it until ~1500 miles (changed three times). After that, I switched to amsoil sig series 5w30... and I can't say for certain if it's the oil or if things are just starting to wear in, but the lifters have quieted down considerably (though still louder than a stock LS7 engine, for example).
For being link-bar performance-type lifters... they're actually not that bad at all, IMO, even with the somewhat tame exhaust system I'm running (longtubes, OR-X, rt.66 B&B cat-back).
So far, I'm really pleased/impressed with this (new to me) LS stuff.... and HPTuners blows away the tuning software available for the 99-04 mustangs. It's great.

What are you running for oil (brand/viscosity)?

The lifters have the same noise on start up cold. It's almost like there are marbles rolling around inside my intake. I think the Fast 102 really amplifies the noise. As soon as it runs for a couple minutes though it goes away.

I've been fighting an annoying tick with Morel link-bar lifters since I installed them over the winter. The tick was bad after a cold start and would be reduced after 5-6 minutes running but would never go away. I tried 3 sets of pushrods (7.266", 7.275", and 7.294") and had noise with every set. I finally installed a set of BTR 7.325" pushrods and am happy to report the noise is gone. The 7.325" give me .100" preload (measured) or about 1 3/8 turns from zero lash to 22 ft.lbs.
