Should I buy it? 1963 Chrysler Imperial

Also, the 413 is an oddball because of the bore size. It is too small of a bore to bore to a 440, plus, only one company makes pistons for the oddball bore size, Egge and they are over 400 bucks. For stock cast pistons. So, if it has not been rebuilt and needs it in the future, that's your only piston choice, unless you go with custom pistons that can run close to or over 1K dollars.

The car is a red headed step child. So is the engine. I would run away. Fast.
