I am a SBF guy, and I have a 302 in my car, and have a spare one just in case. I know of at least four other cobra guys that have radical FEs that have tons of HP in an RPM range that they can never use. Most knew nothing about engines but listened to all the hype of big HP numbers. The same could be said for just about any engine depending on how it was built. Anyway, three of the four do not drive their cars because they are not fun, meaning the engine runs poorly in the RPM range they drive in most . I am considering a Coyote for my next project along with two other guys I know. The discussions we have had goes along the lines of driveability with HP when you need it.

One of the issues I hear regularly is the power range at freeway speeds with the fifth OD issue. Many high HP engines cannot run in 5th because RPMs are way to low for their cam, especially with the .68 fifth. Some can't even do it with the .82. For SBF streetability I use cams with durations at or below 220s @ .050 but then you have limits at the higher end. With the Coyote it seems you can have your cake and eat it to without getting into more expensive parts that break anyway. In a nut shell I would say the allure is driveability over a wide rpm range, not to mention longevity and mileage. But, it still comes down to cost.
