X 2 here. Asking your original question on a MOPAR specific website is going to net a lot of hate mail. You COULD get a SB chevy engine to fit in the engine bay, BUT, it will require a lot of mods that would negate practicality. Your best bet would be to find a suitable engine that will simply bolt in with no mods. Post a photo or two of the Duster in question. If its a solid car, it may be worth dropping a 318 or 360 into. Are you looking for a driver or a race car. If you're going to cut it up and make a race car out of it, do what you want with it. Drop in a chevy mill, and you will have a rough time with this crowd!!:-D
