My dad's got a 390FE laying around his shop. He swears one day he'll get a vehicle to put it in.

I can relate...big time. In the olden days (I've been a machinist building engines for almost 40 years now) I would build an engine and that would motivate me to build or finish car/truck/boat that it would go in. In recent years, I find that I'll finish the engine...and the rest does not happen. That's how the Falcon gasser project came to be...an old friend knew I was sitting on too many engines and needed some motivation. ;-)
