360 or 440?
Before thinking of using the 440 first find out what year it is and what are the internals, Forged or Cast, you could argue that for $500 who cares. If there is a question of it's health you may also want to consider a stroked 400. There's a little more clearance than the 440 especially around the power steering box and built right that 400 will run circles around the 440. Just my 2cents. :burnout:
