    Trying to utilize good parts off of the 68 300 on the 68 Newport convertible, now the dual exhaust will not fit on the drivers side as it hits the torsion bar. aren't these the same frames? Then tried to use the old y pipe from the 383 on the updated 440,this does not work either as it hits the torsion bars on the way up and seems to be too wide. Should the y pipe from the 383 work on the 440, thought they were the same block?

    The 440 is a bit taller and wider than the 383. Very similar, and many parts interchange but the block being taller also makes it wider.

    To answer your first question, the frame on the front section of the car is the same as far as the location of the torsion bars and motor mounts go on the convertible . There is extra metal, a lot of it, inside the rockers which is attached to the door posts and frame mounts to provide added rigidity to the center of the car so it does not "belly" in the center from the lack of a fixed roof. As Polara 500 has noted, the 440 does not use the same exhaust. If you have log manifolds, those are the same, but the pipes are not.

    We are just going to do new duals at local shop rather than cobble things together.
