40 degrees initial!

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

Actually, big blocks like about 34 or so and it's the small blocks that like around 36.
