1963 Dodge Dart 440 727 install.

i've done a 64 using a motor plate and had to hammer the pinch weld flat along with some "massaging" on various bits for clearance. the hump in the firewall needed a love letter from the BFH that read: pound to fit, paint to match. it was a manual brake car without a heater, so other than that bit it wasn't too awful.

fenderwell headers, obviously, but it was still a tight fit.
