first runs US131

Yeah my MT drag radials are 275/50/15,s(26 inch)I,ve put 28 inch slicks on now and am changing gears from 3.91 to 4.30.Should make some difference of the line now,I hope.My stall is a Coan 8 inch 4500 stall.My best has been 11.32@120mph spinning with the 26,s.I find them hard to find proper burnout times,with the weather/temp.Traction sometimes and not other times?
