Haven't run the car in years. It's basically a street car now but might get to the track next season. Can't really afford the race anymore or risk breaking However , I don't remember all the details but it was a 12.20 car with cast iron 2.02 heads (before the eddys were on) Definitely felt a difference after the head swap. I'm not looking to break record or parts , I like to cruise and rip some gears without having to worry about sweeping up parts.
