Even if it is I wouldn't sweat it there was a relatively small number of them that failed compared to how many are out there. If it hasn't given you problems yet it probably won't. There is a guy that delivers boats all over the country that has 1.2 million miles on a 53 block. the TV show "Truck U" did a segment on him. It sucks you got lied to but I wouldnt lose any sleep over it.
