I bought my stang with what it has in it.
So far i found that i have a cai *very obvious* and 3.73 gears. I cant find anything else on my car that would signify a mod other than some crome fuel rails. If my car was cammed or had the heads replaced, is there a way to find out. like if i looked at my timing if i hooked an elm scanner to it or something? Are there markings on stock heads that i might not be aware or?
