No, he doesn't. There isn't that much difference between the 2. He uses a heat treated stator support and heat treated and annealed intermediate drum assembly. Those are the biggest weak points, but even then they will support 450 - 500 HP without them, if properly built. Those parts are the same in a regular 200 and GN transmission. The clutches, the servo, and governor are the main difference between a regular 200 and GN 200. I've broke 700's behind 305's so in stock form, both are subject to failure. Either will have trouble living behind the torque that Popntiac is making in stock form.
