hey, love out of box thinkers. Anything can be put in any vehicle if you have time to work out the snags. If you think you have the skills I say go for it.
I am sticking a 4.6 interceptor in my 99. Chose the crown vic motor because I got it for free. Would of loved a 32v but I'm cheap. My feeling why buy what I can build for less. Try it if it, whats the worst you have to change the plan. Thats why they're called projects, because they are always changing.
