SOHC vs OHV

SOHC vs OHV
I just had a question for those of you that know a lot more about car engines than I do:
What made Ford decide to use SOHC for the 4.0 V6, and OHV for the 4.6 V8, and what makes the OHV design better for the 4.6 V8 engine? Is it a perfomance increase, or is it more about reliability?

Okay I think its a mistake on the Ford website then.

If you read it there it says OHV
BUT
If you read this
http://www.fordvehicles.com/asp/popu...nPopupID=10642
Says SOHC
Or maybe there's something I just don't understand.

Now adays OHV is used to designate engines with have the cam low in the block and use push rods and rocker arms to open the valves. SOHC (Single OverHead Cam) is used to designate an engine that places its cam in the head above the valves. SOHC means one cam above each bank and DOHC means two cams for each bank.
Hope that helped.

Yes i understand what overhead valve means, but if what you are saying is true, why would they say the V6 is SOHC and then write the GT as 4.6 OHV. I mean you may as well go and say SOHC for both. So maybe it is a typo
