You know the newer cars,some drop cylinders to save on gas mileage.I am curious about how they work.Why isn't that felt as a miss??.If they save on gas,I am guessing the system that controls shutting down the cylinder shuts off the fuel and spark.I do know it involves throttle position.Wonder if they really do work or if those engines have problems like fouled plugs more often,etc.

Also-if anyone has heard of a aftermarket system for use on the earlier engines??.You know like SBC's.Wouldn't that be cool to have a system like that on your hot rod??.Cruise mpg in the upper 20's.

Hummm-if cylinders are being dropped,wonder why the other cylinders aren't eating more gas to pick up the lack of power??.
