what up guys i was wondering if any one knows the guy that ownes a 07 silverado nbs he calls it la tompstone silverado i saw a video of him racing and he's running the 12's! or badblackss cuz i wanted to know how hes running in the 12's. thanx guys

 

he put a ls2 block in there and took the 5.3 block out. Thats how he's running 12's

 

 

no actually i know the truck and i believe he still has the 5.3 the ls2 block was somone else there was also a 07 gmc that ran in the 11's with the 5.3 also but that truck was crashed

 

wrong truck bro...Tombstone is one of my good friends...the truck ur mistaking it with is called Thunder, another friend of mine owns it and he did put a LS2 in it. Tombstone is still a 07 5.3 regular, not flexfuel...he has cam, full bolt ons, 3200 stall, servo, shift kit, 3.73s G80...his best has been a 12.7 with a 1.6 60ft...the 07s came out with killer torque down low, he needs 28" full drag hoosiers to hook.

 

that tombstone truck is a motorfreak and it does have the stock 5.3 the other one ur confusing it with is the other truck that runs 12.6 on a cammed ls2 ...seen it run and been in it(tombstone)....i think the 07 5.3 the one without the engine mangament and without flexfuel are the faster 5.3 we have seen that here ...i ran a 12.4

 

my fault. good times if its a 5.3

 

WHATS UP YEAH ITS ME AND AND I RUN CONSTENT 12.7 ON MOTOR IN SUMMER.MY BEST MPH IS 104 AND MY BEST 60 FOOT IS 1.667 AND HERE ARE THE SLIPS TO PROVE THEM, AND THESE PAST THREE MONTHS HAVE BEEN 85-90 DEGREE WEATHER DOWN HERE IN TEXAS 08/03/07 07/11/07 06/15/07

 

Man, the way ya'll were talking, I thought that your truck ran a 12.4 on motor.....or does it??? Your sig says you have a procharger......is it installed??? Sorry for the misunderstanding on my part.

Nice times though!!!!!!!!!
