Yea - I wouldn't go to 4th. When it dyno'd it probably peaked at what, 6400rpm? And I'm sure it doesn't just lay over after that. I'd probably shift at 6800-7000 - whatever you're comfortable with. The 4L80 has quite a bit of space between gears, the converter helps some, but you want all the RPM you can tolerate. 3.73 is gonna work well with that combo.
