how would i know if my engine was rebuilt with better-than-stock parts? i bought it at a j/y out of a 97 bird that had a tree fall on it in katrina. he said that the guy that owned the car had just had the engine rebuilt about 3 months prior to the tree incident. i think i got a really good deal ($550) because this thing runs really well. i was just curious because it seems to have a LOT more power than the previous engine did. i think i actually broke traction into 2nd on dry pavement (awesome for 3.8!) are there any easy ways to see? thanks ahead of time...
