I've got a Saginaw three speed in my 48 and it is worlds smoother than the old transmissions were be they the stock ones or later style non syncro.

You don't need an adapter for that but will need a stick bellhousing for the Olds 350 (one of the BOP) units. plus the Olds flywheel. There should be plenty of bellhousings around because they had a lot of them in Firebirds but the flywheel might be a challenge although they had the Olds engines in the Firebirds too. You might even score a fourspeed in the process.
