I think they had 320 horse. The ticking you heard could have just been the injectors, they do make a similar noise. The Mach 1 has a billet aluminum shift knob, not chrome. Oops I just check this site out:www.mach1registry.com and saw they do have 305 horse. This site should give you all the info you need. BTW what color is it? My fav Mach 1 is the Competion Orange 04... :worship
