In 2008 my boy was running the IHRA Teen class in Tulsa.Had to be street legal vehicle running 10.00 or slower in the eighth mile and had to have an adult in the vehicle with him. We ran our 1982 Jeep J-10 truck with the 258 straight six. When we ran on Friday's with little track prep we dialed 13.50, but when they ran us on Saturday's during a regular race with a lot of VHT we usually had to dial around 14.20. He won five races with that truck that year and it was a blast getting to ride with him down the track. Oh and MPH was usually around 52.
