Yeah. I wondered that, too. Seeing as it was a "big block" guy telling me this. And he is kind of old so maybe he was confused :). Seriously, he's a great guy but 38 did seem high to me. But this guy knows more about Mopars and motors in his pinky than I will ever know. I didn't want to question him
