My car 15 6r80 with gen3r kit mods in sig, his car 11 grand sport ls7 swapped stroker motor. H/c/I said made 630 on old cam setup now has more aggressive cam with open exhaust. Hasn't been back on the dyno with the new cam though. Sounds sick at idle and a sneaky sleeper. Been wanting to run this car for a while. 40 roll and were off each with a passenger I pull half a car on the hit. 3rd gear I pull another 2 cars. Get into 4th and start walking away. Seemed like at least 3 cars before he let out of it. Asked him if he wanted another run and declined. Said his shifts were smooth and let out of it before 4th as I was to far ahead. Clean run just glad I got a chance to open the old girl up.
