Speedway roller rockers for small block?

Yeah it's good to unplug for a while, but you couldn't be a troll no matter how hard you tried.:D
There's some vary well written articles. :thankyou: !

"Yup broke #x rocker arm again" (like it's normal and they have several spares in the tool box.) Your articles sure put a light on how that could be happening.
Thank you.
I know what you're saying. I was at the track one weekend talking to the Mopar racers, and when I mentioned valvetrain failure to one guy, he said "You mean like this?", and dug two broken rockers out of his golf cart glove box. His very next pass he broke the third one. That was all in a two day weekend, and he was spinning the 340 to 7800 rpm. He had me take measurements in the pits to see how far the geometry was off. The rocker shaft was well over .200" too low, and he hasn't fixed it to this day as far as I know. Kinda sad, really.

Oh yeah, a very competent Chevy and Ford sprint car engine builder builds his motor. They just doesn't know how to set up shaft systems unless they are Jesel, and come with a tool.
