Default Building a nice drivable C6...need advice

Ok. No automatic tranny bashing, please.

In a nut shell. When I started out on my CRII build. I had the motor and rearend built to take a 5 speed manual. Well... once we got the body on and the seats in. It was plain as day that there was not enough room in the foot well for my size 12s and a clutch, break and gas pedal. At least not enough to make me feel safe on the road.

The engine dyno'ed at 470hp and 520FPT. I had a C6 built with heavier clutches , bands and all that other stuff. Not knowing what I was doing. I put a 3400 stall TCI converter in the C6 and the rearend still has the original 3.73 gears. With the current setup the car seems to just want to sit there and then as the RMPs get north of 3400, it launches like a bat out of hell. This setup makes it virtually impossible to get on or off a trailer or easily pull in or out of a garage/parking spot.

What I want is a car that drive like a normal everyday automatic, but if I want to jump on it.... well she'll get up and go.

Right now myself and others are thinking we need to take the stall down to around 2000-2200 and gear the rear back towards 3.08 or 3.20

Anyone have some thoughts or experience with something similar?

Thanks in advance!!!!
