Comp Roller Lifters

Comp Roller Lifters 836-16 Pro's/Con's

I have a set withh about 300 passes on 'em. No troubles.

JMO,but I think a Comp roller lifter is a great lifter when used to its limitation. I had a set that had close to 1000 passes on them. That was with a small 726 roller.I'am now a little skibbish w/using that lifter w/really high spring pressures as w/cams in excess of 800" lift. They have a tendancy to spread at the roller.

Thanks for the info!

Just pulled mine after around 80 passes with 1,000 street miles and the exhaust rollers had some spreading where they were difficult to remove but the bearings were all tight. I am going to the John Callies Morels to try to get less oil up top and keep it down at the bottom end. I am having oil pressure problems during shutdown and need the extra edge. You can get the Morels for $200 more.

I've used them in the past, they worked fine with smaller cams.

Seem to spread and wear out fast with big cams and high spring pressures.

I've switched to the Elite lifters in my big motor

What do you consider a "Smaller Cam" ??..lol

I'm thinking .700-.750ish??

Its more about the speed and intensity of the ramps than the lift.

This was my old cam card.. Just wondering if I should go with these lifters again if I were to use the same or bigger cam. Don't want to purchase a set and have lifter failure.

They will work fine with that cam.

Keep the lash tight, keep an eye on the springs and inspect the lifters from time to time.

Dont expect to get 10k street miles and a 1000 passes out of them

Thanks Again for you're info!!.. I think thats the reason one of my lifters failed in my old 501.. Lash was too loose. It is a race motor only.. no worries about driving on the street

Check the lash before every race and keep records, you will typicaly see when somethings going wrong.

Thanks!!.. I'm assuming checking them cold as per the cam card

Big Time Rookie Here!!

Either hot or cold is fine as long as you do it the same each time.

Set them initialy cold per the cam card, the check the hot and see what it is, then record that measurement.
