Help me find the umph in my 360

Stay away from the A41. I put one in my 70 dart 340 and got about 300 miles on it before it just let go. Don’t know if it’s the converter or transmission but it only had a one year warranty and it took me several years to get the car on the road so they would not help me at all.
Oh wow I can't believe it only lasted that long. How many years did you have the transmission before you got the car in the road?
