I just don't see the 4.0 as a performance engine at all since it isn't in anything fast or even sporty. It is a truck engine and it is designed to hauling duties not maximum power. Is that why all of a sudden I'm negative and I should my truck? I love my truck.
No one really makes anything stout anymore. Long gone are the days of the 2JZ, 4G63 and others. Maybe soon though since fuel economy is a big issue now. Ford started it with the ecoboost 3.5. Who else will join in?
