No I havent owned a Lightening, but tony owned one, My buddy billy owned one and so didnt my other friend keith. I know more about them then you think and your Time slip claim for the mods dont add up seeing as All 3 of my friends had the same mods as you with the exception of tonys with the aftermarket built motor and his was the fastest at 12.6/12.7…his truck put down well over 500rwhp/600rwtq at the lake george dyno car show years ago If I remember correctly.
