I am using LKQ1320's 392 in the Royal Canadian and I can attest to it's scale fidelity, Comp Resins Donovan is also good. I'm a fan of injected motors but either one would be a good choice IMHO. Mark Johnson also makes very good motors.
Boy, crank up the way back machine. I built this model back when it was just released and it didn't look anywhere as good as yours does. As I remember the body didn't fit well then either. Nice job Todd
