Where is the car located? If its at/near Fairfield County I know Merc shop that can install the engine for shipping costs - then cut a deal with you to drive it to Carolina.

Restoration is a relative thing - if it runs already, I'd just toss the new engine into the trunk, get the whole package delivered.... and sell whatever you are now driving.

Use value is greatest value of your car.... sittin on cinderblocks it aint worth much.
