5.1) GENERAL DIVISION DESCRIPTION
The Mini-Stock division at the Waterford Speedbowl is intended to be a division with stock cars. The cars are required to utilize OEM standard production parts. If you come up with a part or subject not covered in these rules do not assume that it can be used or done. For example, if the rules do not state that you can use a turbo charger then you very simply can’t. As far as these rules are concerned there is no such thing as a “Gray“ area in the rules. Every rule has a specific intention. If you are not sure of that intention then ask before you get caught or waste time and money. If you receive special permission to use or do something not covered in these rules you must get it in writing and it must be signed, dated and shown personally to the Tech. Inspector to be effective
5.1.1) DEFINITION OF “STOCK” OR “OEM”
