Those memories (with family) are some of the best
The 5.4L would have been 230HP versus the 215 from the 4.6L, so it should have been a bit quicker. Did you guys fab up an adapter plate? The 5.4L has a higher deck height than the 4.6L, just like the 351W vs the 302, so the intake wouldn't just bolt on.
I was not present for all of the things, but the intake did seem to bolt right on, now...did I miss out on some step done without me? Mayhap so. But I did see the intake on the former engine, had long truck runners.
Because the 5.4 deck height is greater than the 4.6, the heads are also farther apart. 4.6 intake does not simply bolt on to a 5.4.
Who knows? Did they make a 4.6L with a long aluminum runner intake? They bought the engine off the back of a truck at a gas station, lol! It may NOT have been a 5.4L truth be told, but that's what they told me it was and what they were told it was.
EDIT:
*Googling, apparently they did. The Triton 4.6L was a "thing". Looks like what I experienced: A near wash in performance (I have no idea what swapping intake manifolds accomplished power wise, but it was rated at 290# torque vs. 270# torque for what came in my vehicle, and 220bhp vs. the 210). Interestingly and amusingly, my current compact SUV has more horsepower and more torque than was ever put in a Crown Vic, minus the 2004+ PI intereceptors, which tied it for HP but not torque. All with a 4 cylinder engine, similar curb weight, more ground clearance, AWD, and far better mpg. Oh the joy of technology!)
