273 to 440 swap

If you have the c-body manifolds and the ability then, sure go ahead. I wouldn't finish the welding until I had everything in place, though. I was concerned about master cylinder clearance (the 440 pictured in those pics is the one in my son's Dart, but when it was in my old Dart). We've put over 35,000 miles on the whole package without a single brake issue related to the clearance.
