There she blows

[QUICKSTANG77]

hmm, after I ran mine hard a couple times after sticking the complete rebuilt engine it with all the mods I also heard this unusal clicking sound under the passenger side valve cover but I can figure out what it is, but my car seems unusaly slow for all the mods that I have. My best time has been a 14.2, with the mods I have I thought I would have hit low 13's or high 12's.
