318 1/8 time improvement
According to wallace, you could.....
Improve your 2.18 to 2.03, and you could run a 9.22, 73.76 eighth, good enough for high 14s at 90mph.
You have 98.5% of that mph now. A tenth and a half better in 60ft can get three and a half tenths in an 1/8th, more in a quarter. I have seen just a good set of tires help a 60 ft way more than that.
