If you are in Rapid's general area, and want a 427 TT, he'll get as much HP out of it as anybody can. What do you want this motor for, the strip? 4 fun? You'll need to do a top to bottom with that kind of HP, meaning suspension, drivetrain, and I hope you won't be cheap and leave out at least a 6 point roll bar to possibly save your life =). Considering all this, again I will suggest Rapid, because they are basically across the street from Phoenix Performance who does chassis and race car prep for lots of racers, and you'll need the one two package for sure.
