Yes stock internals so obviously you can't put 30 pounds of boost to it but the car is quick, fun, looks like a show car and gets good gas mileage. I have friends that have raced these stock 4.6's with no problems. Keep up with oil changes, don't rev it to the moon.
I guess my big block Mopar that went 9.80's at 136 with a stock crank and stock rods was worthless too? New owner still runs 9's to this day.
No it doesn't have the AC, for some reason it was removed when the Supercharger was installed. But my friend works at LKQ and says he can get the AC for someone for a couple hundred bucks, with the Compressor, condensor and hoses.
