1800 rpm in 5th with 2:73s? I think I'm doing 75 or 80 mph, I'll check when I drive to work in a hour.
This chart will give you what you need to know.

The "what speed are you doing at 1800" method is not very accurate, as speedometers and tachometers are not extremely accurate and tire diameter differences can throw it all out. Plus, this chart will help you find the right speedo gear so you can get your speedo back on track.
Yea, the 3.73s are awesome. With some better flowing heads, they probably would be even better, so AFR 165s will fit nicely. You'll want to make sure to have some sticky tires, because the 3.73's will vaporize street tires on a healthy motor. I have 225/50-15 street tires on it right now and I have to feather the throttle through first and second to avoid spinning.

Yeah i meant 8.8 ..lol sorry a typo....Yeah i know my car lugs with 2.73's soon ill throw some 3.73's when i do the H/C/I....
Yep at 80 I'm around 18-1900 rpm, still under 2k. Even with 2:73's my first gear is still useless even second can get hairy. The gear/rpm calculators are they way to go they're fun and pretty acurate.
You could add some good drag springs and shocks to the list.
