Well, you'd want to put a low restriction air filter and an expansion chamber on the two stroke leaf blower motor so it had more power. Then, you'd want to change the fan on blower for more air movement - more boost. You'd need a separate fuel tank so you could pre-mix oil with the fuel for the two stroke. You'd want to hook up the throttles with the same cable so when you stepped on the gas in the car, the blower motor was synchronized. I'd only use McCullough or Poulan - they're the best. You can route the expansion chamber exhaust into one of the Stangs primary tubes so no one will hear the ring-a-ding-ding of the blower motor. Or, with a long enough extension cord, you could just use an electric one - WeedEater brand on sale at Lowe's or HomeDepot. Be sure you have the self retracting, non-tangling cord device mounted on the rear bumper to feed out enough extension cord.
Oh, and you wouldn't want to run either one before about, oh, 9am on Sat. or Sun. morning.
