Here's a shot of the engine/tranny combination we're going to use in the 5 window.  It's a crate 351 GT-40 Ford engine with 362HP.  We're going to hook it to a Tremec 5 speed. This combination should work really well in the car. We're going to make some valve cover adapters to mate old Thunderbird valve covers for a more traditional look. We're also going to add a really nice 3X2's setup to it as we progress with the project.
