500 hp in a 3100 lbs package should run 10.90 at 127.5 mph with a 1.70 60'. I would think that is very possible in a A body. I think the key will be to take as much weight off the front as possible so you can add 100 lbs of weight to the rear of the car and still end up 3100 with driver.
Getting old just means you were smarter than some and luckier than others.
