yeah, im not sure the time/cost is worth it for the 80. especially if your current trans is fine. unless you start modding that 5.3 i dont think an 80 is neccesarry. but if you still want to, i know the later models are better. i forget which years they made the changes but the big issue they changed was the inlet line from up front to several inches back and up in order to lubricate some bearing. you can tell by looking at the location of the outlet line.
