The fastest was 13.0 in the quarter, on 93, but blew a ringland the next pass. The KB107's I have are notorious for that and I definitely didn't have them gapped to the proper spec. Rebuilt over the winter and hope to run again soon. Open diff, 255 street tires. With a locker and traction with higher octane easily a mid 12 car. Full weight 1980 Volare sedan.
Here's a video of the car running back in February
