3.08 was limited to 140 and 3.27 was limited to 127. 93's had no limiter. The reason for the limiter was due to drive shaft speed and vibration, thus why base model cars top speed was higher.Pretty sure all 3.08 cars were 130, all 3.27s were 124ish (same as H and U rated tires, respectively.) Which can, of course, look a few MPH off on an actual speedo.
