3.73 gears for combo?

Just completed my build and am very happy with it. Except that I could use a little more get from the hole and roll. My specs are:
1991 Camaro Z28 5.7
Auto TH700R4 with 3.23 gears
Stealth Ram
280XFI Cam
3000 Stall
AFR Heads
C6 Wheels and tires, rear is 285/35 19 or 26.9" Height, (stock 25.6")

I was thinking 3.73s would be perfect but wanted to hear thoughts and opinions? Driving is mostly short with some highway driving, cruise around 55-80 mph in over drive.

Not trying to drive this car to over 150 mph lol. Just from 0-100 and then have a nice cruising RPM in OD. I noticed my setup pulled to 6300/6400 rpms easy today when it shifted into 3rd. Guessing the top of 3rd would be about 140-150mph at 6400/6500 rpms.
