I Couldn't Put My 40 Year Old Truck In Stock Bc It Smokes. I should have just said screw it and went stock because about 10 trucks got disqualified from the stock class Anyway. I went into work stock. I was up against brand new trucks from the big three. but the old girl dug deep and that turbo picked up the load pretty good. class was 8000 pounds. My Truck Weighed 6K. that was the first time I have ever pulled.
