I remember when I changed my 69 Chevelle to a stocker from a bracket car, It took some time to get under the index, but with all the right pieces we did it. An ati convertor, LeBrun engine and a WA Lee carb and we were there. One of the biggest pay days as a stocker owner is when guys look at the car , look at the Q jet, cast intake , and says how do you go that fast???
