I know the Champ engines and the Commander Sixs have different bolt patterns for the Bellhousings ect.

What I don't know much about is the V8's as I haven't had one for a lot of years that I could use that was runable my question is doe's the bellhousings and flywheel off the V8's have the same bolt pattern as the big six. I have a low mileage Commander six and a 2 speed automatic in a 57 sedan with a worn out 259. Will the six bolt up to the automatic ?

Yes I know it isn't a great marriage as far as a good power combination but I have zero money but a lot of parts so thats the name of that story.
