Help me build a fast 440!

anyone know for certain if the performer RPM wont fit under the flat hood on a 440 dart? Ive heard both yes and no, so i kinda threw that idea out the window....
also, about the cam choice, i for sure want the cam to be one that takes advantage of the wider chrysler lifters..something that was truly designed for a mopar. So you dont think any of the MP cams would be a good choice?
IQ52 has a ton of knowledge and can point you in the right direction. Read some of his motor build threads if you have any doubts. Better to listen to one guy that knows rather than trying combine everything the peanut gallery is throwing at you. You have a good platform to start with and just need the finishing touches.
