actually 65' was the last year for the 413 in passenger cars but they were used
in motor homes thru 73'. as already stated there would be problems using a later
motor and would not be worth the hassle. You could try the same thing I did and
locate a 61' New Yorker or Imperial 413 which is a direct bolt-in and will give
the car a very noticable boost on the road. an aftermarket carb would help
also. spencer 61" Newport (413)
