Gene,
I know that's a requirement for cars traded in for Cash For Clunkers, and that's an unfortunate consequence of the program - a lot of the cars traded in that qualify, like Camaros, Explorers, (not Mustangs - everybody has the good sense to keep them, they're too valuable to trade in

) are going to have Ford or Chevy small-blocks. Net result: bad for us.

It's a shame those engines were ruined. A lot of them, with a fuel injection setup, in a lighter car, or both, could get well over the 18mpg limit for CforC . . .
