    I have used 1969 b-body HP manifolds for a 1967 Dodge Dart 440 swap. They were tight, but they fit well. My question is, are the 1973 HP manifolds the same as the 1969 manifolds? I am doing somewhat of a budget 440 swap into a 1970 Dodge Dart, and already have the 1973 manifolds. I just want to know if it will work. Any and all information is appreciated, thank you, Dan

      Drivers site the flange is turned different from early to late . I used 71 manifolds and cut the column so it was flush with the Firewall . My 69 RR manifolds the flange hit the column shaft. The 71 Super Bee cleared. I also used the biscuit mounts from a Dodge truck they were thicker and lifted the motor. I installed a 383 440 is taller so things will be different with height.

        Thanks.. Definitely saved me some trouble on that one.. Like I said, the 69 manifolds were pretty tight so any differences might cause problems.
