Mopar Muscle sucks. They used to be better, a long long time ago, but even then the tech was horrible. They are a total sell out and would much rather turn everything into an aluminum radiatored, roller rockered, and digital dashed aftermarket shivvy pig. Whatever their primarily generic motors sponsors sell. Not only that but their writing is just so bland. Every story is the same, their attempt at humor is awful, and 90% of their content is written by submission which means they can't stand behind it (I have had them actually tell me that).
Do yourself a favor and cancel the MM subscription, and pick up a copy of Mopar Action. By far the best tech and best content, and the staff has stayed very much the same for a long, long time. All true mopar guys and all knowledgeable. What does that tell you.
