Starfyter Posted December 3, 2013 Report Share Posted December 3, 2013 A V-8 or V-6 with dual overhead cams on each head. Like the new Ford 5.0 or the 6G72. Link to comment Share on other sites More sharing options...
Funky Phil Posted December 3, 2013 Report Share Posted December 3, 2013 No, those are still DOHC. Link to comment Share on other sites More sharing options...
Starfyter Posted December 3, 2013 Report Share Posted December 3, 2013 Using correct terminology, yes. But they're often erroneously called QOHC because of the grand total of 4 overhead cams. As far as I know there has never been a mass produced true QOHC motor. Link to comment Share on other sites More sharing options...
Convette Posted December 3, 2013 Report Share Posted December 3, 2013 Just put a v8 in it. 350hp all day every day for longer than the car will last. Link to comment Share on other sites More sharing options...

As far as I know there has never been a mass produced true QOHC motor. 4.6L Ford V8 used in mustangs, Lincon Mark's and a few other random cars.

Starfyter Posted December 3, 2013 Report Share Posted December 3, 2013 As Phil was pointing out, the 4.6 is a DOHC motor because there are only 2 cams per head. A "true" QOHC V-8 would have 4 cams per head for a total of 8. Link to comment Share on other sites More sharing options...

jszucs Posted December 3, 2013 Report Share Posted December 3, 2013 ^ Toyota/Lexus 1uz fe , 4 (Quad) cam 32 valve V8 . I think you might have missed it above they want to get real technical here and call that 2 DOHC heads not a true Quad IE in any V or opposed format (basilcy anything other then inline) since there is more then one head would need 4 cams per head to "turely be a quad" That got me thinking what about bikes...... then I though somemore and they are actuly DUHC not over.
