Like many people I have always wondered just how much I am leaving on the table with my 4L80e. I found out I can get my hands on a stock TH350 for free or a TH400 with a FMVB for $100. I could pickup a cheap converter from Summit or ebay or something and I was thinking about doing some track comparisons. Anyone ever done anything like this? Better yet anyone got donation TH350/TH400 parts lying around?

I might try to get to a dyno also.

Hey Frank, wanna donate some stuff to prove a point?
