well the bullitt i have been talking about has some good mods starting with C&L aluminum cai steeda tri ax short shifter 4.10 gears mac shortie headers pro chamber and mufflers it also has a dallas mustang speedo calibrator. my big question is how to find out what else is done ( oh there is some serious welded subframe connectors too) main concern is it a stock cam how to tell there is a blue permitex on both valve covers that is not stock and how do i tell if there has been a program or chip put in it
