My 67 Mustang is what I am talking about currently (but I love the others too). I have been tuning on it and it has been getting stronger every week. Yesterday I chirped the tires in third!! Now let me explain the rest of it, it is a manual tranny, I didn't use the clutch, run 245 tires and it was dry roads. I was able to just hit the gas at 40-45mph and get it to chirp! MAN SHE IS SWEET!
