Well, to put it bluntly Devil, No, you are wrong. First off, A viper does not have a SOHC engine, it is OHV. This means that the engine block contains one overhead camshaft. SOHC means one camshaft per bank, which equals 2, and DOHC means 2 camshafts per bank, which equals 4. And yeah, 1 hp per ci might have cut it 20 years ago, but a decent engine makes much, much more than that. Let's look at a few examples.
1 Ferrari Enzo-366 CI=660HP 2 Aston Martin DB7-366 CI=414HP
3 Acura RSX-S-122 CI=200HP 4 Honda S2000-122 CI=240 HP
5 Nissan Max-213 CI=255HP 6 Acura TL-S-195 CI=260 HP
7 Porsche 911-219 CI=320HP 8 Toyota Celica GTS-109 CI=180HP
9 BMW M3-195 CI=333HP 10 Honda Accord EX-183 CI=240HP
You get the picture. And those aren't all even high performance vehicles, either. It is a commonly accepted fact that DOHC engines produce much more power than OHV, that is why more and more cars use them these days. American companies refuse to put them in some vehicles because it is much easier, not to mention cheaper to manufacture an engine that is much bigger with a lot less technology. I guarantee you that if a Viper engine (8.3 liter) was DOCH and was tuned to match European/Japanes specs, it could easily produce 800 hp.
I'm just saying that you have to look at reality here. Granted, a Viper has a lot of torque, but like I said, were it DOHC, it would have a whole h*ell of a lot more.

Pardon me, but OHV means NO cams over the head!! The only reason for putting over-head cams on a car is to reduce valvetrain friction and mass. Yes, pushrods engines can put out the same power numbers as an OHC engine, the position of the cam has nothing to do with available lift, duration, or ramp-angle. One only other benefit to OHC designs is more freedom to open the combustion chamber as in "Hemi" heads. Hmmmm, hemi-heads! Weren't those introduced by Chrysler in the early 60's?? Leave they engineering to the ENGINEERS, and if you think your S2000 with 240 hp can take my '87 Grand National with it's 230 hp V6, bring it on!!
