First time into 10s

Yesterday was our first test n tune of the new season. Last year we ran the small block 408 stroker with headers that were to small for the Indy 360-1 cnc heads. We also had a bad converter to deal with. During the winter we changed out the headers with 1 7/8s TTIs and added a 8" TCS 5000 stall converter. Last year at the track the cuda ran in the 11.60s @116 mph. Yesterday we ran a best of 10.86 @ 123mph. 60ft when from 1.65s last year to 1.48 yesterday. This will make my engine builder a little happier.(he is also my brother-inlaw):| I think we can pick up a little more time with a few more changes.( tire pressures, launch rpm and jetting)
