So took the car to a lumberyard and got it weighed, had to add 150 lbs. Disappointing that it was that light. Also occurred to me that the drive shaft did not have much play, just barely could get it in, the ujoint had to be turned to get it in. Fortunately, it had the bigger trans yoke, so swapped that out with the smaller one just to make there is no bind going down track. Cut 6 inches off the collector to get total of 19. Thinking the 25 inches was to much and hurting mph. MPH is 70 at the 1/8, and 86 in the 1/4, seems like it should be higher than that in the 1/4.

Went to Dinwiddie/Richmond for a CCRA race, and only got to run 1/8. Run one was 9.39 @ 70.13mph. Went from 69 jet to 66 jet, changed timing from 42 to 40. Went 9.40 at 70.02. Had to leave it alone for racing at this point, won first round 9.40 @ 70.01. Lost next round 9.359 @ 70.25 (broke out-9.38 dial).
For the last run, left at 3300 instead of 3000 - it was close to overcoming the brakes - and up 100 rpm on both shift points -5300 and 5800.

60 fts ranged from 1.94-1.91, 330's 5.91 - 5.89.
