WHAT!!!!!!!!!!!!!!!!!
The 5.4 has the same bore as a 4.6 and a longer stroke. They use the same heads. A 302 is a pushrod engine with one cam total located in the valley between the heads. The 4.6 and 5.4 have either 2 or 4 cams and they are located 1 or 2 over each cylinder head.
Whatever magazine you read that out of is mistaken but I think you are just talking out of your POOPAR

Do a 6.1 V-12 from an aston martin. That'll keep you pretty happy. . .

RE: 5.4 question
relax i thought the same thing too, but the 331 stroker that 5.0s commonly do is also a 5.4 so he might have gotten confused

As you've read, the 5.4 is a 4.6 with a longer stroke... The longer the stroke the more stress is put on the rotating assembly with RPM.
4.6 4v > 5.4 2v... There's my suggestion, spend money on swapping a DOHC in instead of a 5.4... You'll have more power and torque... the weak link in these engines is the heads, they just don't flow... increasing displacement still leaves you trying to suck more air through the 2vheads which don't flow enough for a 4.6, let alone anything bigger.
