312 Engine for "D" Code

[Awca12a]

Restoring a 2-door wagon that should have a 312 engine.
Despite not having one yet, I'm setting-up the springs, shocks, etc for the 312 and perhaps adding some extra sandbags in the meantime.

So I'm looking for a 312 Engine.
Plan to make it a father-daughter project of tearing it apart, checking the block, putting it together.
Of course, I'll fail to realize I don't have some essential parts, it won't start and I'll have to call-in the mechanic anyway but that's another situation entirely.

If you have one, I'll be at Hershey in the Fall for sure but willing to take a rolling donor car or arrange for a skid freight delivery.
Of course, if you have one ready to go, that's great as I can then go try my luck on some other area of the car.

Thanks.
