On a 1966 Chrysler 300 with either a 383 or a 413

AB/62 = 383-4

 

[413]

1966 was the first year for the 440. The 413 was gone, no more 413 after 1965 in passenger cars.

Let's leave the industrial and trucks out of this Passenger car question.

The other situation is that the fronts of the blocks are physically different, as indicated in the various service literature and probably the parts manual, too. www.mymopar.com
