Comp R's or Morels? this cam, motor setup will see 7500 regular as a hydraulic setup. Which lifters would you prefer over the other and why? Im leaning towards the Morels. I wish I knew what Mike Brown was running in his CETA. hmmm

I'm running Morels in my new motor. 7800rpm so far with no issues. I ran Comp R's in my LS2 motor to 7500 for a long time. I had a set of Comp R's in my new motor at first but had some valvetrain issues. When we pulled them out. I wasn't happy with what I seen. I would suggest the Morels.

I know some of you (us street racers) are secretive with cam specs, but I am wondering roughly what are the cam specs on these cams that are getting 7500-7800 rpm successfully with hydraulics and how big are the motors? 7800 out of a solid roller is baby ****, but out of a hydraulic.....you have my attention.

I'm thinking about upgrading the lifters this winter, and havent decided on the Morel, or the new GM lifter. Price is not the issue, just want to get some more info on both lifters.
Don't know much about the new GM's, but the Morels have a good history and can handle high spring loads. The offshore boat guys use them a lot, and a car engine is babied compared to a marine engine.
FYI: My latest Crane newletter also indicates they are introducing a new maximum effort roller lifter as well if you want to investigate them as well.

The Morel lifter for the LS1 was specifically built at the request of multiple cam grinders because they new this engine platform would be thrashed. Tolerances, oil band location, material, wheel diameter, valving, are all areas that were looked at to live in this application. Also the Morels are 100% rebuilidable so after 3 or 4 years of 7000 rpm pulls you send them back, have them rebuilt for $185 and you have a new set of lifters.

In my case in got my Heads / Cam / Lifters / Push Rods and the related parts from a renowned tuner that doesn't advertise on this board... no worries, everything will go back there for any service.
My question is related to a customer that bought a second hand LS with Morel's and need a rebuilt.
Is the address where the Morel's are build always :
Gear Company of America Inc.
14300 Lorain Avenue, Cleveland, OH 44111
