Came with a 292 that was supposed to be out of a 1955 bird.  Had a 56 block and 57 heads.  Is this a 57 distributor?

Thanks

Knowing what it takes, you didn't accomplish it with your loose change, and there's more than just 1 cu. in. difference between a 427 and 428; but you know that.

Thanks for sharing all the info.
