z power thanks thats a cool design but i dont think it would hold up at high rpm and it only changes lift not duration but it would be better than 1.6 straight ratio. I might look into buying this system depending on the $. and i thought of another thing i have to put oil around the gear when im spining it for timing due to windage on the weighs unless i make it all internla with a cover on the gear.

If memory serves me correctly, back in the 1960's, there was a centrifugal cam sprocket available for the SBC that allowed variable cam timing.
Anybody else old enough to remember that piece?

Gee, wasn't that the same time period the last dinosaur died?

Have you guys looked into the technology used in Formula 1 engines. I don't know much about them, but I do know they run between 17-20k rpms. They must have a relatively sophisticated valvetrain to open and close valves that fast.
