Opinions/experience please..........

I am performance oriented and could care less about "sreetablity". I run a manual tranny.

My question is this. Just how durable are solid roller lifters when used on the street? I only plan to put a couple hundred miles a year on the street and the rest of the time the engine will be raced.

Would a once a year teardown and inspection be acceptable to make it live?
Thanks in advance!

68rs406,
Thanks for the input. I am going to go ahead and do it. My application is a 427 bbc, and the cam is .680int .660ex [email protected] duration.
I figure if I maintain it, it will live.

I ran a small block with a much more aggressive Lunati solid roller for 8,000 miles but I did nothing more than set the lash every couple of weeks. I ended up with a few broken inner valve springs. I was wondering if I was just lucky?!?!?

Here's a post from another site where a few guys posted their experience with solid rollers. Some are getting several years out of them, some are not. Cam lobe profiles and spring pressures have something to do with lifter longevity I'm sure, but I'd be careful and do plenty of research before you fork out the big $'s for the parts. If you go real mild on the lobe profile to save lifters and springs, why bother going solid roller at all?

I built a 377 for my '69 convertible. It's running aluminum bowtie heads, strip dominator intake with an off-road "z" cam (same grind as a '69 z/28). I put solid lifters and 1.6 roller rockers in it and have never had any problems. The car is driven a couple hundred miles a year on the street. Thw worst problem is fouling plugs from not driving it that much.

Buy good quality roller lifters once and be done with it! Do not buy the cheapies, you will end up spending 10x what you saved when one breaks and takes a motor with it. I ran a smaller oval track roller for a long time on the street with no troubles, it was 262/272 @ .050" with .550" both sides, and I used 1.6 rockers to bump the lift to .585". It ran often to the 8K mark in a little .020" over 302" and never hurt a thing.

good choice smits, you'll love it. just buy good parts and be done with it. esp. lifters and springs. you don't need springs made from "unobtainium" either, just a good quality manufacturer, i'm running isky. solid rollers are great in a lot of ways, even the more mild ones usually achieve more lift and more agressive ramps, with similar duration numbers. they plain just make more power than a comparable flat tappet. (although comparing the two is totally apples to oranges). my cam is quite docile sounding at idle, imo, and makes around 13" of vacuum, plenty for my power brakes, and rev's like a banshee. my buddy is a big block fanatic, and he ran a solid roller in a basically factory Ls6 in his wifes car, and she drove it a ton and raced it a lot as well, no problems and easy 11.60's on a dot tire and factory suspension. she would get crazy at times and rev it to 7K, and it would still be pulling (although probably out of its power range). i could go on, but you get the idea, i love 'em . and of the number of guys i know that use them in street/ strip cars (including myself), have never seen a lifter failure, and only a couple of valve springs, maybe. in fact my machinist buddy said the only roller lifter he's seen fail are the ones herbert sells, he wasn't sure why though. good luck with it, you won't be sorry [img]graemlins/thumbsup.gif[/img]

Thanks for the input guys.
My springs are brand new Lunati electroplated roller springs. I am using titanium retainers and 10 degree locks. The Cam is a Crower regrind. I have a rev kit laying around somethere too. I may as well use it too.

Also, don't skimp on the rockers either. I've ran a solid roller for about 8 years now and have never had a failure when using good parts.

good point hals. make that rockers and pushrods, for that matter. i'm running comp pro magnum rockers and 7/16 studs, and a set of manley swedged end pushrods, all somewhat spendy but really should be used on any motor, flat or roller tappet that is built with performance in mind, imo. as you go up in spring pressure, valvetrain flex is a big issue. the best bet is shaft rockers, that will be a future upgrade for me. good luck with it, lets hear how it runs when your done [img]graemlins/thumbsup.gif[/img]

Isky Rollers, Manton pushrods and Jesel shaft rockers have been my saving grace over the years.

If you are going to run solids on the street, you may want to look into Comp Cams Endure X roller lifters. They have a machined groove in the body to allow oil to drip on the roller itself at low rpms. Part numbers for the Rat are 866-16, and 888-16 for the Mouse. Summit has them listed as Hydraulic rollers on their website, but it is incorrect, they are solids.

I plan to use my Herbert roller rocker arms and a stud girdle. I think it will last a while. The use of good components and regular inspections should ensure a long street life.

I would avoid these myself; there have been many documented problems with them including my own experience. They do have a higher than normal failure rate according to Comp, if you can get someone to admit it to you. They handled my claim professionally, but it would be better to not have a claim at all. Isky and Crower roller lifters seem to handle the day to day driving a lot longer.

Does anyone have experience with the Crane roller lifters' longevity? Solid and/or hydraulic?
