About 140-155



Road and Track and many other magazines topped the GT out at 138mph. It should be more but fifth gear in the five speed is to tall for 225hp. With tighter gearing it will increase or if you modify to over 300 wheel horse power fifth will become very usable. If you have an auto trans it will be 138 as well because of poorer power transfer.
