Default Re: '67 Shelby slow build

Took the car to Bakersfield on two weekends. 2 check out passes 11.73 and 11.30 to make sure it went straight, shifted and stopped without overheating. My tires were really old and it was spinning pretty bad and I had some rubbing issues. Purchased smaller tire and took the car back out this weekend. 1st pass the car pushed through the beam for no time. My fault, it was my 1st time using a 2step on the brake pedal. (Previous car was S/G car with tran brake)
Lowered the 2step to 2,800 and was able to get the first full pass on the car. It ran .400 under the B/SA index (I think it's closer to B weight than A as I haven't weighed the car yet) that run was made at 95 degrees and 3,524 altitude density. Next pass was 1st round win as the other guy broke out due to the cooler morning weather. Next pass was a little messed up as we were held up on the line while the previous pair had issues getting off the track and I red lit. I ran it through at 10.76 at mid 80's temp and 2,900 ft.
I haven't touch anything since I got it running so there's room for a fair amount of improvement with tuning and driver education.
