Took out the duster this weekend ran 11.475 with 4.11 gears running through the traps at 6200. Whould i be better to step up to a 456 gear change and hopefully run 7000 through the lights.And would that get me in the tens. I have a stroked 360 to 426 dyno at 628hp at 6800rpm i have a 28.5 tall tire
