But for every advantage there comes a disadvantage. Sure a DOHC engine with the same displacement could possibly have more hp and tq. But, you can get much more displacement out of a OHV engine despite having far less physical size. There are some big block engines that are physically smaller than the Coyote engine. Now can a Coyote engine make anywhere even close to the power and tq of a big block? No. It can't.
All this talk about engines and high revving DOHCs and such...yet the Mustang is still the slowest of the 3 Muscle Cars by far. Both in a straight line and on a track. And that is even after a massive upgrade done to it, lol!! High revving DOHC engines are for posers who want to FEEL like they're going fast. Pushrod engines that make gobs of torque down low and then carry hp/tq thru it's entire band are for when you actually wanna GO fast.
