It's very easy to put it in. Hooking it up is the hard part.

Seriously- go for it. Do something different. I'd buy a Chevy truck with a 440 in it. You might want to look at some of the Mopar musclecar sites and suppliers. There are several kits out there to swap 440's into A-bodies (i.e. Darts)- you might be able to use parts from those to get the frame-side motor mounts, if you're not into fabrication. Use the Mopar Performance electronic ignition conversion for spark control- beats the hell out of points or trying to adapt to the Chevy system.
