Out of the box thinking. They designed and patented the linkless roller lifter back in the 80's when working with McLaren on the buick indy stuff. Now their dual roller lifter in the Fuel and top alky classes dominates.

Merlin,
The valving has been changed compared to what Eaton, most preferred over the years, had run. Due to the tight tolerance held on the ID grind on the hyd. rollers, you are able to run more spring pressure on the lifter to maintain the enertia damping at higher rpms. This also equates to higher rpm without getting into valve float. 2 well known cam companies did extensive testing on these before purchasing.
Weight I don't know. I don't have a gram scale. Maybe Chris or Terry can compare them since they now have stock.
Materials. Morel has extensive backgrounds in what metals to be used for such endurance applications. The axle, roller, and bearing materials are all high grade alloys designed to run for years.
They goofed and did not send me a solid, sent 2 hyd. samples. As soon as the solid gets here I will take a picture.

Merlin,
The lifter should take 150# seat and 400# open no problem. RPM range will be related to ho agressive the ramps and flanks of the cam lobe that they are on. With that said this lifter has gone on average 400 more rpm then others when tested on the Spintron. Light weight valvetrain is for high rpm. Hyd. roller engines are not considered high rpm engines. The hyd roller was developed to produce power downstairs and in the mid range of daily driven cars. Is there power in lighter spring loads and lighter parts, yes. Is it a good idea for modified street cars, my opinion no. I would not worry about light valvetrain parts.

That, and the engine's oil pressure and the viscosity of the oil...

What where the numbers Chris???
Light weight valvetrain is for high rpm. Hyd. roller engines are not considered high rpm engines.
OOPS... guess I'll have to tell my five liter guys to stop going over 8500 rpm with them...

Ed,
Get to work!!!! By the way AT should be giving you a call. I gave him your number yesterday. I'll get you some numbers. Your order has shipped also.
Crain,
They are designed to be a "drop in" replacement for the OEM so I asked Morel and yes they take the std preload.
Merlin,
I was referring to where valve float occured. The new lifter was tested against OEM and aftermarket pieces. No comps lobes were not used, Ultradyne's were. Harold Brookshire and John Reed developed the inverted flank stuff years and years ago.

Thanks T/A. The LS1 hyd. is on the left, the right is retro fit for 55 to 97 SBC. Note the difference in the height of the upper OD of the lifter. The axle and roller are held in with radial wire clips, so the lifter is totally re-buildable.
