Why can't Ford make a naturally aspirated engine with 400 hp and 400 ft. lbs?
Then the buyer can add a blower or turbo like Lingenfelter does. Those cars are BAD!

Like any high performance n/a engine worth it's weight, you probably wouldn't want o just slap and blower or turbo on it because it's high compression. Unless you like running 5 pounds (or less) of boost.
If I had forced induction I would want to crank up the boost.

32v's but not OHC I believe.
My opinion, the English language is full of words and phrases that don't always get used correctly, but everyone knows what is meant. If I need a tissue, and ask for a Kleenex, a Puffs will work just fine. My point is, that if we all understand what's being said, who really cares. Most of us here understand that OHV is pushrod, and OHC could mean SOHC or DOHC, and those who don't eventually figure it out. Not a big deal.

I will agree with the gm talk about ohv engines the camaros and firebirds are fast they don't even have a dual exhaust set up like a stang due to the torque arm they use 
, but still one of my friends has a WS6 thats running high 11s all stock internals naturally asperated and on a 3.23 gear out back. for 01 vs 01 the ta is making more torque 23 more at 2000 less rpm and 10 less horses at 800 less rpms.

As for the whole GM:Pushrods::Ford:OHC argument...waste of time. It's a packaging and cost issue...not which design makes better power. Ford can and has made excellent pushrod mills as well as GM has some worldclass OHC engines.
For the actual topic at hand.
There are as many pros as there are cons with both. Neither is inherantly better than the other.

the flat head is a push rod motor too (IE. Briggs and Stratton), so you maybe you can just use the differientiation of a pushrod motor and an ohc motor.
I thought they went to OHV engines for efficiency. The old flat head V-8 100 hp Ford had
poor fuel mileage, but was bullett proof.

I'm glad that at least some are paying attention and are laughing at this. I agree with BVFD1983's original post. A '56 Chevy, '73 Pinto, '93 Mustang, and a Honda lawnmower all have overhead valves.
Perhaps the only manufacturer to continue make a "flathead" or non-overhead valve motor in the last 50 years is Briggs & Stratton. The OHV nomenclature has been driving me nuts ever since I bought my newest Ranger with the 4.0L.
