Do these look like the new retainer clips Comp is using in their current Comp R lifters? I found these in my oil pan during the oil change. Is this the problem people have been running into with them? It still runs great .


Quarter is used as a size reference.
Sorry for the small phone camera pic.

 

yep...

 

Shoot....! What do you guys recommend as a durable replacement? I am running .608 inch lift and spinning it past 6500rpm.

 

solid roller

 

Stock lifters. If ya got enough spring and not too much they will work. Lift has nothing to do with it.
Stock will take ya to 500HP and 7000RPM's if sprung right.

 

sorry to hijack thread;but i'm building a forged bottom end lt1 with a cc306
cam and everyone has told me to use my old roller lifters.(i'm old school flat tappets).should i do this?

 

If the roller's turn good and there are no cracks in the lower part of the body and they were OK when ya removed them,you bet use them. Ya can adjust them 1/8 turn down and make them just like the Comp "R"'s.Just check them first.

Get the right spring's 130 seat and 300-350 nose,this is after break in as they will loose 15-25 lbs after a few heat cycles.Might look into the beehive springs by Comp.

 

i think they are ok in that respect.i don't have access to the spring info at the moment;but i bought the ones for the cam.i know they are comp's though.i'll probably try to post again when it come time for valve adjustment as i'm not sure about the "adjusting to comp r's thing"thank though

 

Y're welcome,anytime.

 

Since we're on the subject of Comp R's...

Are these lifters known to be noisier than most brands?

I'm thinking it may be the rocker arms (Pro Magnum)

I just setup a valve train on an LT1 using the baseline method and a feeler
gauge.

I have had two sets of roller rocks, Crane and Scorpion which were somewhat
loud; but these Comp R's w/ Pro Magnum are annoying.

Should I be concerned?
