350 at the flywheel is a massive amount of power, especially in a Stratos type car.

While 12.5:1 is the ideal afr for horsepower, it's rarely the ideal ratio for knock-limited power. It's quite possible the tuner really did know what he was doing and used the richer mixture at high rpm for a good reason.
