Anything I should know about the swap. Can I use the same bell housing, motor mounts, exhaust manifolds, etc? The 440 has the crank drilled for the pilot bushing. From what I remember it can be a direct swap, just wanted to be sure. Thanks for the anticipated information. 6573520-CarShow2017.jpg (94 downloads)

You are saying the exhaust manifolds from the 383 will work and bolt to my exhaust system? Thanks for the quick confirmation of what I thought.

Only potential will be the exhaust system if you have an H or X pipe , the 440 is wider and the manifolds are about 3/4" higher up .

Dunno if you are planing on use the 440 exhaust manifolds but juts in case I would keep the 383 exhaust manifolds you actually have... the diff on years could make diff flange exhaust bolt holes indexing making don't match with your pipes flanges.
