    engine swap

    First posting, new member.
    83 coupe deville, former deisel, dealer converted to 350 olds, hydroboost brakes, 700r4 trans.
    Is it possible without too many mods to swap olds engine to 425 or 472,
    looks like dealer did a very good job of the deisel swap, nothing missing, everything is intact.
    Suggestions, comments welcomed, tech site directions would be helpful.
    Car is destined to be a strong cruiser, nothing more.
    Her name is Babs2, Babs 1 was a 68 Chrysler New Yorker coupe, saddly she is gone.

    A 403 or 455 Olds will drop right in with the 350 motor mounts and tranny. Transfer engine accessories including starter and have a blast. Did the Diesel conversion to 403 myself about 10 years ago. A muffler shop fabricated a custom dual exhaust system. Doug-J
