A girl that works at my daughter's pre-school has a Silverado SS, well it's actually her boyfriends truck. I was rapping out with her last week and she said it has a 411 stroker, nitrous but don't know how big of a shot, headers, exhaust, and someother bolton's. I asked if they ran it at the track and she said it ran low 12's.
I might go rap out with the bf and try to set up a track day. Not much street trucks at the drags here.
