I just picked up a nice 440 with kerker exhaust and was wondering if i could get it to fit in my 550 but as i looked at it the 440 and 550 manifolds i realized that they are different and also realized that their isn't a way to switch them so Is their an aftermarket manifold that I can use to put this exhaust on my 550? I have looked but I cant seem to find a clear answer. Thanks

these motors are basicly the same but the 550 has a larger bore. the 440 manifold you have will bolt up to the 550 motor.
