Want to step up to a solid roller this winter from my CC294s flat tappet. I want to run a street solid roller roller. I see they have a oil groove in them for idle in street situations. I want to stay under .650 lift. Will these lifters survive in a street car that gets run around four to five thousand miles a year? graemlins/beers.gif

DO NOT USE THOSE LIFTERS, DO NOT, DO NOT, DO NOT. I know of three motors (1 was mine) that had roller failures with those lifters (all less than 5000 miles)

The biggest problem with those lifters is that the axel is press fitted into the body of the lifter, and there is no retainer clip. With a normal roller you can tell when the lifter is going because the lash will start to increase but the retainer clip should keep the lifter from falling apart. With the Endurex there is no retainer and due to the axel being pressed into the body of the lifter, when it starts to wear the axel egg shapes the hole in the lifter body. Then the axel backs out and knocks a piece of metal out of the lifter bore of the block. If you are unlucky it backs all the way out and dumps the entire lifters assembly into your motor.

I got lucky when I caught mine. I tore the motor down and was inspecting the lifters and when I turned it sidways the AXEL FELL OUT !! I could not believe it so I checked the rest and found 8 of the 16 axels could be pushed all the way out with finger pressure and 4 more could be pushed out a little ways.

Thank you!!! smile.gif

Reliability of solid rollers seems to be a big concern, even with the new ones designed for "street use."

Friends of mine running solid rollers have also experienced similar failures with the Comp Endure-X rollers. Right now the hot ticket seems to be the Crowers with the HIPPO (hi-pressure pin oiling) option but longevity/reliability is still up in the air. I haven't heard of any failures... yet.

Things that will help them live a long life on the street are reasonable spring pressures and a cam profile conducive to street use, with less agressive opening/closing ramps and thus less spring pressure requirements.

Totally off the subject BUT still is the subject..

Check this out but it sure isn't a stock to aftermarket change!!

The last ones, the RollerX lifters!!

If they could make these in a stock bore size, except for the price I bet they would be dandy's!! Imho..

Does anyone have any longevity info on the Crane solid roller lifters? I have these in my 406 and would like to know if they are likely to survive with some street miles on them. Thanks!

If you are going to run a solid roller, especically on the street, get the best roller you can buy. The Crower Severe Duty with the HIPPO option or the Isky Red Zone lifters. Both are excellent lifters, but I would lean toward the Isky lifters due to the fact that they are rebuildable and the Crowers are not.

Each set will set you back about $450-500.

Ron Iskenderian told me that his Red Zone's with a street profile roller would last easily 20k-25k street miles. He told me of a small block Chevy with them installed has gone 30k miles and is still going.
