There's a lot more stuff floating around for the Chrysler Six. Headers, intake manifolds, cams can be bought new and even aluminum heads will be on e-bay, or at flea markets, from time to time.
That ol' Packard is an awesome engine and, if it's in good shape, it'll probably last forever. Man, they're HEAVY!!! Packards were popular for irrigation pump engines, when I was a kid growing up in Florida...a hundred years ago. In stock form they'll probably pull anything you need to with it. However, if you want speed parts, you'll have to build them yourself. Sure would be good to see one powering a cool street car, though!
I assume you know there's 'small block' and 'big block' MOPAR sixes. The Plymouth 217s and the Dodge/Plymouth 230s are 'small blocks'. The Chrysler and DeSoto engines are 'big block' sixes. There's even a 265 dual carb version used in some big Dodge trucks, back in the early '50s. (even rarer and bigger ones were made, but someone else will have to give you the 'poop' on them)
There's several great Inliners, who are working with the MOPAR engines, so there's a vast amount of expertise for you to draw from here. Welcome aboard!
