I know I heard of some 12.6 stock cobra’s but most are 12.8-13.1…mach 1’s I see a ton are 13.8 or so…but I have seen a few run low 13’s, for the 01 GT most I see stock (I guess you can call them stock since everyone I have seen has flowmaster) run around 14.0-14.5. But is your times are legit I give props that is getting everything out of those cars for the most part. (in pgh) I’ve also seen a certain red ws6, only run a 13.7… so i guess that means ws6’s can’t run faster than 13.7 stock? The 2003-2004 Mach 1, and the LS1 F-body is a dead heat race… both have actually run high 12’s bone stock, but in the hands of a good driver, typically run low 13s all day long --- _[View the full topic](https://forums.speedlife.net/t/bolt-on-ls1-vs-bolt-on-4-6-stang/187380)._
