I understand the cars on track are nothing like the cars in the showroom, Ford, Chevy, Dodge, Toyota still have to make the engine block that the teams use .
Now 2013, things are going to change, the new cars are going to look a lot closer to the showroom counter parts, which is something the manufacturer's have been lobbing even more so since the COT came out in 2007. So next year the cars on track
will look like whats at the dealer, so that connection will be a lot closet then it is now.
