Jeff, when you make that swap, be sure to look for the adapter that moves the starter to the passenger's side of the block. That was the big problem when putting an Olds engine in an early Ford frame- - - -starter/steering gear interference, and I'm pretty sure it would be worse on a stovebolt. Those adapters were made by a company called "Trans-Dapt", and I think they're still in business. Whether they would still have a bellhousing adapter in stock 50-something years later would be the 64-dollar question!
