Trust me there's plenty of vehicles with 4 wheels that go faster then my bikes do, but yeah I'm more accustomed to 0-60's in the 1.6-2.5 second range depending on what toy i pull out of the garage to play with so the F150 would be pretty boring to me to race.

So whats that ZX run for 1/4 mile times?

its all about task and purpose.
If I want to do Autocross I will drive my Porsche 944
the F150 is for towing, hauling and winter
with that being said, I would love to see the event but I would not participate with my f150
Bottom line up front: to each his own.

Haven't done a proper quarter mile run yet. It's wrapped on jacks at the farm for the winter. The rear-wheel steering system needs work, but I might just delete the HICAS system to lighten it up. It needs to go on a diet anyways and I'm gonna shave the engine bay. Still have to finish the interior... But, I also have a 1970 New Yorker and a 1953 GMC truck I want to get started on...

Yeah, the ZX, Skyline and a couple more have the HICAS system. It's a really weird feeling taking a fast corner because it doesn't do what you expect. The rear-wheel steering is not directly linked to the front wheels. The computer decides which direction to turn the rear wheels, and how much depending on G-forces, speed and how fast you crank the steering wheel.
At first going around a corner, it turns the wheels in the same direction as the fronts, like this
//
//
Then it will snap them the other way like this
//
\\
At slower speeds it'll turn them like the second example.
The the rears don't turn as much as the front. Takes corners like it's on rails. Makes a quick lanechange super easy because the car basically slides sideways and doesn't actually change the direction it's facing

I am really interested in this as well. Currently have a 5.0 but trying to decide on 3.5. I know the 3.5 eco feels faster due to low end grunt but I would be curious to see if the 5.0 makes more power at the top end. Would 1/4 mile times be about the same or does the 3.5 win hands down? Not that I want to race a truck, just more curious about where power is made.

I honestly think a 3:73 geared 5.0 and a 3:73 geared 3.5eco would run the same 1/4 with the right driving techniques. 0-60 will be the eco, IMO.
Thing is, you just haven't seem anyone do a apples to apples comparison. gearing is crucial on the 5.0. The 3.5 eco is not benefiting from 3:73's as much as the 5.0. It just hits harder and sits at its peak HP, the 5.0 needs to get in the upper rpm and it makes more HP.
I hope that makes sense, here's another way to put it. The tq wins down low but when Tq and Hp cross(X) in the rpm range, Hp starts to get its advantage.
