Converter is too tight. Need a good 8" that goes about 5 - 5.2K. A 10" that loose will be too inefficient.
That low gear will be quick, IF the track prep is there. When you get tired of spinning, put the 2.45 back in it. Rear gears sound about right for ~6500 in the lights.
Once it's sorted out - 10.80s in decent air @ 120.
If the results don't match the theory, change the theory.
