I'm wondering if Corvette will ever get cam in cam technology like the Viper. I don't know if Chrysler has those patents locked down or if someone like Dephi owns that.

That's interesting, I wonder if hydraulic valve control will ever really take off (like Fiat multiair, though you can just vary lift ala Valvetronic for low power consumption and simplicity). Seems like you should be able to get some significant amount of lift variation through the lash adjuster with a high rocker arm ratio or whatever it's called. Thanks for the info.
