question about a 5.4?

[97gt-svt]

Ok like I have said before I dont know that much about the modular motors, but I am under the impression that 4.6l blocks are intercangable between 2cam and 4cam heads. If this is true then is it possible to use a 5.4L block and put 4cam heads on it since it is pritty much the same as a 4.6L only stroked longer. This is probly a really dumb question but I was curious so I asked it anyway, if so dont flame me to bad. :??:

yes

Yes they are interchangable but the intakes are different due to the wider valley

What kinda power differences are expected after the swap?

it is like going to a Cobra R motor. not as powerful but it would be close to their numbers. If you go to a 5.4 motor then you must go 4v. I have experience with 5.4 2v and it makes too much torque and not enough horsepower and it kind of lags.
