before changing anything else, gear it properly. 24 or 25 tooth on a 76 spur, as said earlier works out about the same ratio as i use with a speed passion 8.5 in my 2wd.
gearing up will gain both torque and speed but make it a bit smoother. less timing will add more torque and take away top speed, more timing can take away torque, smoothing acceleration and gain top speed but everything runs hotter and less efficiently
