Stock or underdrive?

I just bought a 2000 SS and im trying to figure out what all it has. Some stuff is obvious, longtubes, cam, etc... Some are more difficult, underdrive pulley, cam size... Anyway can anyone tell me the diameter of the stock crank pulley?

If it looks like a 3-spoke design it is more than likely the stock pulley. If it is a solid pulley than it is more than likely an aftermarket. You would have to measure it to know how much it is underdriven if it is aftermarket.
