I remember reading that they were supposed to be available for big blocks soon.
Anyone have any experience with them?

You might want to contact Bob (rmbuilder) on this site.

I am using Isky hydraulic roller lifters. When I ordered my cam and lifters, I was told by an Isky tech. that they are Morel lifters.

Are these the hydaulic roller lifters that are supposed to be good to 6500 RPM?

I spoke to Isky today and was told that they purchase lifters from Morel.

I have not got a chance to use them yet. I just built this motor. It only has dyno time on it so far. I have heard good things about Isky or Morel Lifters. I hope they work out.

Morel is a tier 1 supplier so there is a good chance that many of you may have seen their product branded with other suppliers names. The engineering on these pieces is outstanding as evidenced by their users (John Force/McLaren Engines/Top Truck and Busch Teams.). I will have a technical sheet available right after PRI with some amazing durabliity testing results.

Tomcat,
These lifters are manufactured to very tight spec tolerance and depending on spring pressures and valvetrain weight will extend the useable range.

Tomcat,
The Morel uses their own petal valving in the body of the lifter. With this and the tight tolerances that Ed is able to hold, yes the lifter will take more rpm then other hyd. roller lifters. On the the solid side, I have used the stuff for years now with NO failures due to mfg or lifter fatigue. If Isky is admitting they are using Morel as a supplier then that speaks boat loads of Morels quality.

I plan on using the Morel hydraulic roller lifters on my next lifter change.
