why swap out a 190hp sixxer for a 202hp sixxer?
so much time/money for 7hp dont you think? again, unless im missing something (And itd have to be something pretty danm signifigant)
their is absoulty no point in swapping a weak v6 for another weak v6
The 4.2 makes quite a bit more torque, and with the mustang intake, there will be a bigger gain then 7 peak HP.
Kind of like swapping out a P.I 2v that's rated at 260 for a 4v that's rated at 280
seems like a lot of work for a little gain in ADVERTISED RATINGS. But 9 times out of ten, the swapped motor will have some changes done to push its peak power well over what the original rating was.

The gains will actually be more then what ford rated the truck 4.2. Using the mustang intake on it will net a bit more peak HP.
Some have been pretty successful with the 4.2 swap. With a set of ported heads, ported intake (mustang), and a custom cam, it can make close to 300rwhp. But doing those things are not too cost effective, and only someone that is dead set on keeping the sixxer would do that.
