Baker,
Here is my guess if its running right, assuming you are a mile high or so:
3800lb w/driver, tools etc
Torq 214 at 3400
Powr 175 at 5000
3.39 60ft
13.08 at 56.4 1/8 mi
19.93 at 72.4 1/4 mi
5.55 0-30mph, all 1st gear
14.51 0-60mph, 1st & 2nd
7.98 50-70mph, all 2nd gear
84mph after 1/2 mile
93mph flying mile
99mph top speed 3 miles later

Now, that was with the stock single muffler!!
If you have an open pipe:
3.37
12.94 at 57.3
19.67 at 73.8
5.46 0-30mph
14.00 0-60mph
7.45 50-70mph
85mph after 1/2 mi
94mph after 1 mi
101mph after 3 mi

Hope you get some approx times so we can see where things are!
