New best 60'

Ok guys Im all ears on how to get my duster in the 10's 340 stroked to a 416 10 to 1 eddy heads flowing 280 nothing left in .them 586 lift hydrolic roller trans brake and 430 gears. best i have done is 11.42 @ 116 158 60 ft.... Help

What does it weigh? What converter and what does it flash? Cam duration at .050? Where is it installed at, cl? How much initial and total timing? Intake and carb? Who's headers? Tires? You're shifting it where, rpm's?

For comparison, my 340 was 11.4-1 with ported Edelbrocks, 294 cfm at .650" lift, flat hydraulic, 236/242° @ .050", .592/.586" lift with 1.6 rockers, installed at 104°, Weiand X-Cellerator with a Quick Fuel 750, 9.5" converter that flashed 5200, 4.30 gears on a 275 drag radial. At 3240# it went 11.60 @ 116 with 1.52 60' on pump 93.
