Hello everybody I have a 99 Durango slt 5.2 the 5.2 is on it's last leg I was thinking about having a mild build done on a 5.2 long block. now I'm really starting to think about doing a 5.9 instead. so what I need is info some are saying the flexplate and converter needs to be changed others say the balancer and flexplate only need to be changed and everything else will bolt right up. thanks for any info and help

 

also wanted to know if anybody knew if the sct turners work on a 99 5.2 durango. I'm only finding listings for 5.9 durangos
