Mike Bradford Uses Octane Booster in '70 Mach 1 Mustang

Our 1970 Mach 1 has been in the family since my wife purchased it as her first car in 1977. We met and married in '80 and rebuilt and mildly modified the engine in 1982. It has run like a watch since then. The engine has a compression ratio of 10.5 which in hindsight is a little high, but it does pop out the exhaust nicely. Last night I was going to the drag races at New England Drag way with the car, which saw it's last strip run in '83. So, it's mostly street driven with only 93 octane gas and lead replacement occasionally. While at Auto Zone in Concord NH I was at the counter and saw your product. It was an impulse buy but you now have a lifetime customer!!! The last time it ran that good, I spent half a paycheck on race gas. I never knew how sluggish that gas made the car's performance. Unbelievable!!! I haven't tried a lot of other octane boosters, but hell, why do I have to. The most noticeable difference was when the gas pedal was mashed. Instant power, no ping, and it shut off without any dieseling. Well, I just wanted to drop you folks a line and if you ever need a nice looking grabber green Mustang for an ad somewhere, give me a call.
