Daniel they don't have Clevelands as far as I know. Most of their engines are Windsor based.
I have the 427R engine and other than a few modifications like headers, flywheel, water lines its a pretty simple swap. I have the nice original Cleveland protected for the next care taker of 1306 if they want it.
Your deposit doesn't sound unreasonable, however the time you have been waiting is.
Not sure of contact info but try Russ Fulp here in So. California many people happy with his Clevelands.
