Are your trans internals still stock? Stock converter? Stock cam? How much boost are you seeing?

When I was running 5-6 psi with stock cam, my stock high-mileage transmission was doing pretty good. Then I did a cam swap. About the second week of daily driving, the trans wasn't very happy, so it got built. After that, I pullied-down to 11-12 psi, and smoked the 3-4 clutches(red Alto) and the Kevlar band. Then it got the blue Alto clutches and a Carbonite band, but not the billet shafts. 2 or 3 months later we were ordering the billet shafts. :nunchuk1:

One time, before the cam swap & pulley change. In 4x4, 14.30, in 2 wheel(spun to the 1/8th), 15.something. It didn't feel very fast.

This is the 4x4 run, against a 2008 Mustang. I apologize for the quality, my 13 year old daughter recorded it for me.

Trans is stock except for vette servos, 40k cooler, and the HD2 kit is hopefully going in within the next few weeks (when Tootall has a free weekend, haha). It was rebuilt 42k miles ago. Stock cam, stock manifolds, 3.3" pulley (so I'm thinking 7-8 psi). Probably 370-380hp to the rear.

I don't think I will pulley down because of the IAT issues since I live in Houston (where it's 90+ nine months a year), but I plan on doing a gt2-3 cam and LPP's within the next year or so.
