Here in Michigan, I just sent Rich’s motor to my engine guy. For $3200 the entire motor was rebuilt, and that’s including all the parts except the cam, which Rich ordered and took there. This was a 273 Commando rebuild, where the custom pistons were $900, and the rings for them were almost $800. Bring your motor to Michigan, Darryl at Auto Parts Machine Shop will do it right, at a fair price.
