GM is still making pushrods other than the LS series, and are introducing VVT in a 3.9L V6(OHV) they are working on.
The next step up is computer controled valves, camshaftless engines.
As all the engines sold in Europe and Japan (bar some American imports), are fitted with either one or two OHC's no advertisements make specific mention of that issue any more. All GM products sold in Europe, except again of the products coming from the States have either one or two OHC's. It does not make a marketing difference. What is may be high tech for US consumers has become bread and butter for everybody else about twenty years ago. GM obviously is not convinced of the superiority of the OHV engine to re-introduce this in other cars produced elsewhere. Just wondering why that is.
I also read recently that GM is considering to make a 4-valve head for the LS-2. It might close down the weight gap between the LS6 and any DOHC engine considerably.
Probably you also think that Chrysler decided not to futher develop their supercar (M4/12 or something) because it was fitted with a Mercedes V12 DOHC and not with a V10 viper engine.
