How tractable was it down low.


Twin-ignition, indeed,....

It made good power from 5000-7500 and had the typical little "hiccups" between 3500-4500 as ALL carbureted race engines do,...

Exhaust systems make a HUGE difference in drivability and throttle response, as well as HP. 911 motors are quite sensitive about this.
