75 Nova U/SA

Update - Spent a day last weekend doing test and tune to try and get jetting/timing set, and get some 1/4 mile times.. Best was 14.87 at 1700 D/A. Most were 14.92-14.94. Best was with .064 jet and 40 timing.

So readjusted the valves based on some ideas from this site, for racing this weekend, and HOORAY went 14.84 - UNDER NHRA 1/4 index for the first time. Two other runs 14.91 (changed shift points) and 14.90 first round elims(dialed to high-opponent had way better lite and I dialed a little to high-broke out). The track had issues with the MPH clocks so no 1/4 MPH data for any runs.
I also put on new front tires-same size-and consensus was less rolling resistance since riding on the new tire 'nubbies'-LOL.
