My friend and I but the timing down 2deg for racing because the car isn't certified and have keep in the 10s.The new converter has been loosen up but still good for 175 shot.Well we stay in the 10 and run 10,1 @ 135.Wen we got home and found the timing turn down 6deg but not bad for right off the trailer.Time for winter up here have to wait for next year.But it was nice to get out after 5 years with no motor.Much tuning for next year.
