There was a cammed/header/etc camaro running 13.5s. Another heads/cam 5th running 13.3s. I think I'll stay with the basically stock mustang. Both camaro guys said they have between $6-8k into their cars, I got $780 in mods total. $250 for the cai, $300 for the tune, $100 for a used x-pipe and $130 on control arms.
