Welcome to FCBO, with regards finding a 440 that's not too hard, Craigslist ads have them all the time, its more of a case of being careful to buy a good runner and don't pay too much, there is a big range with what people try to charge for one. i have paid as little as 300 up to 800 for an engine. Plus you will need to get the bigger radiator and change the primary exhaust pipes too. Oh and change the transmission too. Plus the mount plates on the engine block will be different but the rubber isolators will be the saem, depending on what year you get too, the later engines from 72 on i think (can someone confirm?)have totally different mounts.
