5.0 stockers/ distributors

I tried the distrib. that was in the car, and today a reman. from Autozone. Same resuts with both distribs and 2 timing lights. The timing is dropping from 30+- at idle to 15+- at 3000 rpm. Funky thing is that one time it even showed 15 at idle too. Holley Commander guy said it could be a bad TFI module. To me it now sounds like the Commander is moving it around but not showing it on the laptop. I'm picking up a new MSD distrib in a couple hours to try. Got a bad feeling, it's gonna just be same problem/ more $. The Holley guy also said it could be worn Timing set, or worn cam gear. Hopefully not, they are a lot tougher to swap out. Thanks for the ideas.
