With the 4.10's I trap 115 @ 6400 in 4th. For a blown motor 3.73's would be the way to go IMO. If you cam it and are able to spin it to 6800 you'll see about 122 with a 28" tall tire and 4.10's. 3.73's will get you 125 @ 6400 in 4th. I plan on blowing my motor soon, just hope the 4.10's aren't to steep. I'll probably have to start in second then.

I run a Circle D 3K stall. It does not hunt and my shift completion RPM is up a few hundred. I have it set to lock at 100 MPH right when the HP curve starts to dip. The 3K stall is perfect for a blown application. Also make sure it is a tight (type A) stator vs a loose (type B). Blown motors need the tight stall so there not wasting HP/TQ. I have not raced the new verter, but plan on doing so this weekend weather permitting. There is a lot of tuning involved with the 6L80E and no-one at the present time has managed to gain full and instantaneous lockup at any given speed. I am actually working on this with my tuner and upon completion the lockup converters will be able to be used to their designed potential.
