It's a big price to pay to convince the technophiles that OHVs have many advantages over DOHCs. It's a price GM will have to pay (unfortunately) as no matter what real world evidence is presented to people, some just stop listening. Nothing will satisfy their 'requirements' more than knowing their engine's valvetrain is actuated by DOHCs.

Of course, DOHCs are inherently more refined that OHVs... so that also plays a part in buyer's minds when forking our dollars for high-end vehicles.

 

I know but I just thought that they did when the the Gen III changed firing order from the Gen II.

 

What about the Cadillac V12, is that for trucks only?

 

I think the people that know the difference between DOHC and OHV are likely ones that will be able to look past their basic nature and see how each has its benefits. Most consumers would hardly know the difference anyways. For Caddy- sure. For Corvette- no need.
