Mitsubishi had a version a year later, and it fell out of use until Mercedes brought it out on a V-12 in the '90's, followed by Chrysler on the Hemi's in '04. With oil prices in '08 "...many manufacturers..." turned to variable displacement controls on their larger engines to bring their CAFE numbers down, and to offer more fuel efficiency.

Roger,you first posted link is there.It was my mistake looking for a www. ref.

We all have looked at add-on's like propane,natural gas,hyrogen,Gear Vendors O/d's,etc to save on gas mileage.Many having big downsides.So for me to understand these systems more completely wouldn't be a bad thing.I just think when you consider what Edelborck has as a aftermarket add-on done with their EFI systems although very expensive,maybe a conversion for this is out there.But as I said above,first I need to understand them better and as with everything,there is a up side and a down side.
