Nope. Check the bore stroke and cam profile. Not to mention the valve size.
It's an rpm screamer just like the 6.2l. Modern engines can harmlessly take advantage of rpm that previous engines couldn't. Long stroke engines like the 5.4l had massive torque, everyone here called them gutless. Let the trans make torque. Tape over the rpm gauge, and let the engine eat.
It'll waste the 8.1 though. The 8.1 was a low output tow beast. Very wheezy. But that's how work engines survived back then.
Have you seen the published dynograph?
Peak power and RPM range/limit is irrelevant in this discussion.
Notice the torque curve. Greater than 400 lb ft starting at just 1500rpm
Its an absolute stump puller, regardless of high RPM performance.
And is exactly why Ford went with it for its superduty line.
With a very flat, very broad torque curve that starts at such a low RPM, it should be one heck of a motor.
Compared to that of the 6.2... where you need to be beyond 3500RPM to get into the fat part of the torque curve
