Quote from Bully Friend:
They check every winners engine after a race and as far as for Montoya's and Pruett's car being the same the set ups on them were completly different.

"but I am talking about the engines, which theoretically should be the same"
Engines never come out the same one is always a little better and set ups make a lot of difference of how cars run. A set up can make a car run away from the others. It happens all the time.
You can take two brand new Corvettes right of the line, theoretically the same but one will be faster.
