Different size torque converter knob 170 vs 225?!? Are you kidding me?

Dan, I respect you and your knowledge, but either he takes a gamble on a machine shop or he waits till the 225 is rebuilt or he pays big bucks for a custom made converter. Those are the options, and given he wants to drive the car while the 225 is being rebuilt, his cheapest option is to have the snout turned down. But it's not our car and the op will make the ultimate decision.
