Regardless of the generational weight differences, a bare 5.4 NVH block weighs 210 lbs. vs. 159 lbs. for a bare 4.6 iron block. Throw in the 5.4s heavier crank, rods, intake manifold and timing chain cover and you're looking at nearly a 100 lb. weight difference between the two engines once assembled and dressed. Then there's the 8.8 vs the 9.75.
