Interesting, I sold a Dart that I thought had a stroker, per person who sold it to me. Well, took said car to my buyer, they drove it, was completely satisfied on how it ran, power output. Told me, "it runs very good" Well, sold the car. Get a call a few days later, seems it is not a 360 stroked, but ONLY a 340. Well, I refunded some money, it is only right, BUT they told me "if it were only a 318 I would not want it" AFTER saying how good it ran!!!!!!!!!!!! What difference the numbers on the block, they look the same.............
