OK Ron, I think I understand what your having trouble with.

Your math here is absolutely correct. A standard bore with a 3.75" crank is ~377 cubic inches.

However, the industry refers to a motor with a 3.75" crank as a 383, which is my point. When quoting the displacement of a stroker the industry assumes the motor is 0.030" over bored.

A Cleveland motor with an offset ground oem Cleveland crank, 3.70" stroke, has always been referred to as a 377. This is again because the industry assumes the block will be bored 0.030" over. If the block were standard bore, it would only be ~372 cubic inches.

Are we on the same page now?
