the carb is a holley 4150 with a kit from Bow Tie Overdrives.
I just ordered a "Corvette" Governor and will take it apart and weigh the parts, reassemble and see if I can get the shift RPMs up.
As for the hanging RPM, you may be right, because I really have to mash the throttle for it to rev up, and I may be pulling the cable too far.
Here is a question for someone...... If the governor is not calibrated properly(engine speed too low), can the TV force the tranmission to generate a higher RPM? In other words, if the governor isn't properly tuned, does this limit the transmission speed in all conditions?
Thanks for the comments so far.....
