If it has extraordinarily low gears, then a swap would be the way to go, if it's running around on the interstate in second gear then we can start to chase why.
Note the shape of the trans pan and number of bolts or post a pic of the pan and we can help. Greg

Based on the info from another post. The tranny is a TH350. As for the rear end. . . did not see any markings; I will check again tomorrow. However; with the rear end jacked up.. . both wheels off the ground. 1 rotation of driver side rear wheel resulted in drive shaft rotating 2 revolutions plus about 10 degrees.
