At the risk of sounding like I'm preaching (I'm not), I'd ask why you'd trade out of something you know and like into something that you're already afraid you won't like?
It isn't that I am afraid of it I was more caught off guard and confused. It makes sense to me now and I am intrigued by the engine option of the truck. I am looking for a newer truck so this fits the bill as I didn't want a 5.0 or 3.5EB. Not to mention my 5.4 3V has 124,000 miles and will eventually need an oil pump, timing chains, tensioners and phasers along with new exhaust manifolds. All are common 5.4 3V failures. The parts alone are north of $1,200 for OEM not to mention the myriad of specialty tools I would need to acquire, the down time and that doesn't include any repair problems or account for having to drill exhaust studs out. I am not afraid of a new truck, I am afraid of what my current truck can do to me in terms of down time.

Pulling a 5000 pound trailer in my Friend's FISO with this engine, the most RPM it saw was 4000. And that was when he was slowing down in Tow/Haul mode.
I am honest-to-goodness impressed with this engine. If I was searching for a later model truck, I wouldn't even bother looking for a 5.0 - this engine would suit my needs perfectly.
Yes, it will hold 4K RPM with a good trailer load uphill but it not only pulls it, it will accelerate while doing it. My FX4 has 3.73 gears and gobs of low end torque. This truck has major nanny controls on it. I wish I could experience this thing full tilt with no nannies dialing back my timing on the low end. The intake, exhaust and tune woke this thing up big time. The factory tune runs it lean below 3K and above 3K enriches it up a touch. You can feel a noticeable bump in power at 3K, presumably from an enriched mixture and cam timing kicking in.
