Sounds like a solid build. any thoughts on a 4L80 over the TH400?

I'm curious about your answer to this one too.

I went from a 200r4 to a Th400 in a single turbo SBC g-body but swapped gears from 3.70 to 3.08 at the same time. The car felt like it accelerated much better but I don't have any data to back that up and there's more factors that changed besides just gear ratios; torque converter, for instance.

I can see advantages to both transmissions. Has anyone managed to squeeze either trans in an e36 yet?
