320 Straight 8 new rebuild

I believe this to be a 1952 motor. Presently set up with a Edelbrock 4bbl on the factory intake. It’s never been in a vehicle, it was professionally rebuilt about 15y ago, tested and then carefully stored inside. It’s 0.40 (?) over, has a mildly custom ground cam, and is 12v converted. It comes with an installed Bensten transmission adaptor kit (as well as it’s original bell housing) and a 15yr old new rebuilt Turbo 400. It can be seen running - smooth as silk.
