Jon, I don't know where it will be set. I put one tank of mid-grade as an experiment. No difference. I thought it would make some difference in the timing set but it still pinged a little. It will be a few days until something else gets done I am having a medical procedure done on Tuesday. I still in the belief that the Hei is at fault because it was the one thing that was messed with before the mileage dropped off. If I don't get it sorted out I am still doing better than a lot of people with 235 engines. Jon, I looked at your truck, nice job, I will have to look at my brother in law's Corvair carbs, he stores it with me in the winter. Jerry, as far as paying, they do a lot of things and don't charge me because they did most of the work on it from the beginning of the transformation and they really like the truck.
