Putting A '77 Slant In A '64 Valiant?

Your car is a 64 with an automatic, correct? Do you still have the PB shifter? If you do chances are it is a 64 trans not a 69 trans, and you will need the bushing. The engine will go into the car with the later oil pan, but the front of the pan will rub on the "K" member. You really should use the 64 pan and pickup, along with the 64 engine brackets. You will also have to modify the throttle linkage and kickdown linkage to use the super six setup in a 64 "A" body. Keep the 77 electronic distributer and add an electronic ig system (mopar or HEI).

PS: the reason the super six is rare in Ca. is they could not be sold new in Ca, as they did not meet the emmision specs.
