My teacher used to work at the Ford factory in Mich. And he says when they built the 4.2 motor the first motor was putting out more horsepower and torque then the 4.6 so they had to retune the pcm to make the 4.6 had better numbers but that is what he said I couldn't find any thing about it

I don't understand how a non boosted v6 could be putting out more than a v8 that comes from the same builder. it goes against all logic. but. anything is possible. and yes new plugs and cops are a big reason a motor losses power.

I think the 4.6 is a very slow motor I wouldn't buy an f150 with one but the 5.4 is a whole different motor I think some people don't understand that we are talking about the 4.6 and the 4.2 the 5.4 would stomp all over it all day long
