All metal rocker arms


Freddie

Recommended Posts

Well, all rockers are all made of metal...

but the Brit ones are forged steel.

You only need them if you're spinning 8k with 13mm+ of lift....

the stock ones will survive up to about 7500 with sane cams,

the billet will go further with less sane profiles...

and if you're breaking anything at this point, you

really need to know a lot about your spring pressures and

ramp angles. The arms don't like floating AT ALL!

I run a Schrick 316 cam and matching Schrick springs.I've busted a handfull of stock arms. I heard alot over the years about the steel rockers and never heard anything bad. Unlike almost all the aftermarket ones availible. Just tired of playing around. I would rather pay $2000 and not worry about it anymore!! If they work?

They do work. There were horror stories a few years ago

about the billet aluminum lash pad material, but the latest is that it's

pretty well sorted.

I'm saddened to hear that you're having trouble with the 316, as

that's the profile that I'd like to run.

What springs are you using?

Ok, I did this whole search yesterday at lunch and even sent it off to you but it got lost in the mix somehow... So here it goes again...

L.H. Owen is the maker of the steel rocker arms... I saw one of the Elva Mark 7 or 8's at the Wine Country Classic with L.H. Owen valve cover and intake manifolds on the M10 in it... Asked the guy about them and he said that L.H. Owen has been building and racing BMWs out of England since the mid 60's... His motor has never had a rocker failure.....

The Cunningham and Brecht Historic Trans-Am cars all use em'... to 8200RPM.

I believe Bill Watson has built a few motors with them.... Maybe Terry Tinney has them in Jeff Hecox motor too??

Eric Kerman from Long Island NY has a long history of building excellent M10 motors... I tried a Google search to find his contact info but came up w/ nothing. He did used to sell stroker M10 motors out of the Roundel classifides a few years ago...

I found this contact info..... for L.H. Owen

I'll dig up an old thread...

... have just come across this - apparently Schrick are making steel rockers (at something like US$240 each.

Excuse the poor Swedish translation (not that I speak a word of Swedish myself):

Oh, you've tried PPM's and they are wearing out too. Good to hear - well not good, but I'm glad to know that. I have Ireland/(Skidmark original style) ones that are toast.

Sorry I can't help you with the steel ones. I haven't heard bad things about them but not many have experience. Where did you get those?

Well, apparently Perry's "Skidmark" ones have been fixed so they don't kill cams.... And Ireland's have updated rocker pads as well.

Fred went with Ireland's updated ones and they are working well.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
