They are job specific, generally measuring linear dimensions. The templates that NASCAR uses to verify the shape of the cars are a type of go no-go gauge.

Here is a Wikipedia article: http://en.wikipedia.org/wiki/Go/no_go_gauge

Is their a type of go-no-go-gage in a sprint car teams tool chest?

A tape measure could be considered a "go-no go" gage, when it somes to tread width, and wheelbase, covers a lot of territory, but for the most part, is item specific, a thread gage has one end "OK", other end not in spec. Bob

A common go-no-go gauge used by racing officials is used to quickly determine
if a carburetor or injector stack bore is larger than legal allowing a motor to make extra
horsepower. Like the double ended plug gauge in the Wiki article one end will be the
maximum legal diameter. The other end will be a slightly larger diameter. If both
ends of the gauge fit inside the bore it is oversize and illegal. No need to accurately
measure the bore with a micrometer, it is quickly determined to be legal or not.

A go-no-go gauge can also be used for adjusting the valves on an engine. It eliminates the "feel" of what the gap should be. If the valve adjustment you are trying to achieve is .003 of an inch then you would use a .002 (go) and .004 (no-go) and that gives you .003 valve lash. The feeler gauge has the .002 and the .004 built into the same blade.

Hello Jackie
When I was an official with the 360 sprints here in Michigan I had a gauge that a friend made. It was used for checking the intake restrictions. Minimum 3" long and 2 3/16th inches across, it was T shaped and was very useful.
As far as Go / No Go gauge it could refer to any almost any tool used to check for a legal or illegal piece.
Being an official could be a tough job but I had a great group of drivers to work with. And I had a close friend who would guide me (chew me out) if I didn't.
