Not against pushrod motors one bit........in fact the GM LS motors are awesome!!! Even though that 500HP is a 427, the packaging is phenomenal.
And I agree that but for a few examples, Ford doesn't utilize the advantages that a 4 valve DOHC motor could offer.
But I still believe that a Variable valve 4 valve motor will make as much if not more power than a much larger displacement 2 valve motor. Ford's 5.4 Cobra R and Toy's new 5.7 come to mind....(even though the 5.4 doesn't use VVT)
And I will also concede that I don't understand Ford's past thinking concerning retooling for what could have been a killer OHC motor and saddle it with 2 valve wedge type chambers.
I know it was SUPPOSED to be an EPA thang.....
Useless trivia time.........the LS motors are about 10 years old. The NEWEST GM architecture is DOHC multivalve in the inline 5 and 6 cylinder motors.

Your multivalve OHC comment is right on IMO.
