So first couple passes out this year with new dart and 340 have been good. Started in 11.80's @ 112mph. From there we went up 2 jet sizes and and dropped plugs heat range from RC12YC to RC9YC. 340 responded well and ran a tenth faster. So last weekend we set timing up from 35 degrees to 37 and installed the caltracs mono leafs (caltrac bars already installed). First pass out was a 11.71 @ 114mph and then I got these 2 timeslips.
