bolt on ls1 vs bolt on 4.6 stang

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
