I have about 10k on my comp 848 lifters and send oil through the exhaust pushrods.919 comp springs 225/550 sp.I was eating the 829's up with k1000 springs in under 1000 miles .10k in 3 years of street beatin and many trips to the track,I am pleased .The reduced lobe aggression on this cam with the reduced spring pressure seems to have been the tcket for me .I will pull the hemi out within the next few weeks for PM and CSI investigation.I am looking foward to see how everything has held up.

I mean idle time at a stop light with the oil hot as hell and idle at 1,000 RPMs.Kills the springs.


I see, hot springs from driving around, and hot oil; then run at idle when very little oil gets on the springs to cool them.

This is why it is a good idea to use lifters with EDM and send oil up the pushrods.Lots of oil to the needle bearings at idle,oil to the adjusters to prevent galling,and a little extra oil spraying on the springs.I lost 15 lbs of oil pressure hot at idle but is well worth it IMOP

I was using the K1000 for years.When I changed the combo,I went with the complete COMP set up so they could not put blame on the non-comp part if there were to be a problem.Ther has not been a problem I will be sending these comp 848 lifters back to be rebuilt just for preventitive maintainance.Will also go through the valves and check spring pressures.

Hemi-itis, You seem to have had sucsess using the AMC lifters in your Hemi, I like the idea of pushrod and axle oiling in a street motor. However many posters on this site say you cant use these lifters without bushing the block, Having used them do you see anywhere you could run into problems with this type of lifter/

When I first primed the system with the intake off,I was concerned because cold,the oil was hemmoraging from the top & bottom of the lifter .I was thrilled with the way oil came up the pushrod sending extra oil the the exhaust valve .So,I put it together and ran it.Had 80 lbs cold on fire up,after hot 25/35 idle,75 lbs @7500 rpm.I have the MP roller rockers which have not needed any real adjustment in 3 years and 10k mikes.I wish I had the Barton system and spray bars but,,,,,,,,,,,not in the budget.But I do not worry about idle time,sometimes takes 20 minutes on a friday night to get mt spot in the cruise parking lot. One thing I must say,when your pullin' outta the lot and whack the throttle and just blow the tires away that is the hardest on the roller lifter and rocker.The roller bounces of the cam sorta in a "FLOAT" and reaks havock on the valve train.CONTROL YOURSELVES!!!

511 hemi with a Cammotion 247/252 roller. Comp 929 springs set at 160/420. I put about 21000 miles on this . I changed the springs once and the Crower Rollers once.
The Bronze gear is in such good shape , that i am reusing it on the upgrade i am in process of putting together.

I sent the Crower Rollers back for a rebuild ( with about 11K miles on them) and Crower said they were nearly perfect. I had them rebuild anyway for about $190.
I used Indy rockers on the setup ( for sale BTW) .

New setup will use Stage V rockers , 254/262 roller with Comp 943 springs set at 250/587- and the same bronze gear
