Here's a picture of a rocker that we did for a 356.

And BTW. Our 356's rev 8000.

None of the above. If there was truly a will to make them, then we would.


Simply wrong,

a number of years ago someone floated some aluminum roller rocker arms for 911s...

in the end the cost/complexity/benefit of them never exceeded that of the off the shelf Porsche rockers.

Someone has made improved 911 rockers..

and yes I realize Im not talking 914 now

Clay Dopke used take cast rockers, stress relieve them, shot peen, polish, etc..

Do me a favor and tell me the MOI of a stock rocker arm, and one of your lightened rocker arms?

By no means am I slamming your work... just making an observation that this is on the extreme end of performance benefits
