I have an upgraded 69 with stock 3.0SC , 911 trans & Electromotive ignition. I did not do the swap, but you can read about it here.

The car moves out much better than a 2.4T I drove. The 901s first gear is the weak link. If you plan on doing hole shots, then you should consider the 915. Otherwise, the 901 should be good for around 225 ft/lbs of torque.
