The idea run for a car with 122 trap will be 1.51 60' and 10.86. You are real close to thar mark right now. That tells me your converter is in the ball park for the power you are making. I would make sure my fuel system was up to snuff as that would kill the mph. What are your 660' numbers?

Getting old just means you were smarter than some and luckier than others.
