i had a car like that. with dirty carburators, it hit 90.
sloooowwww. but it was a 4-speed tranny.
your speed is a ratio of ([RPM]x[gear ratio])/([rear end diffrential]x[circumfrence of tires])
complicated? not really. you don't have to worry about it too much. General rule: cars have higher top speeds than trucks. the more speeds a transmission has, the higher it's top speed.
there are exceptions to the rules, but those are good for thumbnails.
torque and horsepower only help you jump off the line and speed up faster, respectively. a 5hp motor can get you up to 200 mph, but you'll have to wait a few days to do so
for the record, my speedo goes up to 110, but i hit 150 on a track, and wasn't maxed out
