Not all Specials for 72 were 340 cars. I had 1 that was 318 2bbl. Ofcource I could be wrong and a 318 was swapped into it. I also had a 72 340 swinger. When I moved I couldn’t take them with me so I sold the 340 car and gave away the car with the 318 in it. I guess it’s possible it was a 340 car also. I know where the 340 car is, but the other car I have no idea if is still there or not. Kim
