Breaking in the new motor
This is my new best: 12.17 @ 109.7 1.77 60'. Full weight (minus spare), stock 20's and tires, 1/2 tank gas, DA -200.
Motor: 418 LS3, AI CNC 243 heads, Futral cam, ARH 1 7/8" headers (with cats), JBA exhaust, CAI, pulley, Efan, RPM stage VI tranny, Vig 3200 stall, BUT my CR is only 10.1:1 as the motor was built for boost, & still running stock intake manifold. Slip breakdown: Fastest Run: Next fastest run Best mph 110.408 (1.840 60') 60' 1.778 1.771 660': 5.003 4.998 1/8: 7.751 7.747 1/8mph: 88.945 88.897 1/4 : 12.175 12.178 1/4 mph: 109.730 109.496 This was a 12.19 pass.... Here is the 12.17, I had switched to night shot mode on my video camera, and it didn't pick up the timing board very well. |

Motor sounds good. It's gonna be insane with spray.
