Missing motors
So you are looking for your original 340 motor for your duster? Correct?
Yes any 340 car is worth restoring to original, but you have to be careful with the money you put into it as they tend to not command a high price and are not deemed highly collectible.
But thats the crowd that never owned or have driven one, especially back in the day. Guaranteed they won’t tell you how they got their doors blown off by one. I smoked so many big block corvettes its hilarious.
I also am looking for the original engine to my 69 swinger. Good luck with your search.
