Steve is MOPAR Happy. My really cool, well restored 1970 Challenger never quite ran tops, despite my finding a variety of helpers. Today I had great expertise from a young mechanic. He diagnosed an obscure engine build problem, made that adjustment, then made the cascade of timing and carb adjustments. We took it for several "spins". The big 440 engine squeels the tires with ease. Boys and toys...pour me another Chardonay to celebrate
