Confusion between GM and GMC designation?
- Have a question regarding power plant designation on the M4A2's twin pack GM 6046 engine (2x GM 6-71 Grey Marine diesel engines). The GM stands for `Grey Marine' so is this a licensed off shoot of the GMC 6-71 Model 6004 (General Motors Corp) similar to what was used in the British Valentine or are we talking about two different engines? At a glance it is easy to think GM meant General Motors instead of Grey Marine. Some clarity would be appreciated.
