Manual

3.55 = 2304 rpm
3.73 = 2421 rpm
4.10 = 2661 rpm
4.30 = 2791 rpm
4.56 = 2960 rpm

top speed w/ 3.55s, 5th gear @ 6798 rpm = 236 mph
top speed w/ 3.73s, 5th gear @ 6780 rpm = 224 mph
top speed w/ 4.10s, 5th gear @ 6787 rpm = 204 mph
top speed w/ 4.30s, 5th gear @ 6769 rpm = 194 mph
top speed w/ 4.56s, 5th gear @ 6771 rpm = 183 mph

Auto
.70 ratio, 80mph, at X.XX:1 rear gear ratio

3.55 = 2602 rpm
3.73 = 2733 rpm
4.10 = 3005 rpm
4.30 = 3151 rpm
4.56 = 3342 rpm

top speed w/ 3.55, @ 5789 rpm = 178 mph
top speed w/ 3.73, @ 5775 rpm = 169 mph
top speed w/ 4.10, @ 5784 rpm = 154 mph
top speed w/ 4.30, @ 5791 rpm = 147 mph
top speed w/ 4.56, @ 5765 rpm = 138 mph
If I'm reading this correctly, would 4.10's in an auto tranmission be roughly equal to 4.56's in an manual transmission? Or am I backwards?
