sleepers....how fast and how plain before it is one?

to me, a sleeper is something that runs a lot faster than one would ever expect. So, if it looks like a ..... examples:
  1. 100% bone stock 340 Duster, wheels, tires, exhaust manifolds, etc., and it clicks off a 12.10 at 110 mph, that's a sleeper.
  2. Or a typical cast head small block at a local car show, ya know, headers, sun pro tach, full interior, traction bars with a 60 series tire, looks like a 13 second car but it goes high 10's, that's a sleeper.
  3. Your car, without the chute, but having a cage, I'd guess a typical 408 stroker running at least low 11's.... so yes, if you click off a 7 second 1/4 mile pass, then that's a sleeper. And those that say "you are not fooling anyone" are not being honest, because without the chute, nobody would guess 7's by watching it drive by. Even if they guessed 10's by look'n at ya at a stop light, they missed it by 3 seconds, so you'd be raising their eyebrows as well :D
thank you sir. if i had a different brand many would be suspect for sure. however owning a dart nobody even the rare wise guys would guess a single digits street car from a mopar. add to it the ugly looking color patina, dosile idle i figured it wasnt a snoring boring sleeper but it was more of a"holy s$%# didnt see that coming" kind of sleeper.
