440 into a /6 duster

Let me put it this way. If your car is al setup for a V8. Swapping to a 440 isn't too big of a deal. I've done 2 440 a bodies. I know all the tricks. Use the wealth of knowledge here. It helps.

For the record I deleted the heat and heat and AC on both of mine. I don't really drive it under 40 degree weather.
