hydraulic clutch in A body

I finally got around to making the hydraulic line for my setup (pull cylinder, stock fork, Centerforce DF clutch and throwout). I'm surprised at how low the pedal effort is, and I'm worried I need to decrease the pedal ratio (or move the fork hole closer to the pivot than the stock hole, or get a bigger bore master). With the Lakewood scattershield there's no way to see how much plate departure I'm actually getting with the clutch pedal fully depressed.

Does anyone know how much travel is required, measured at the original fork actuating rod hole? I think it's 1" but would like to hear from anyone who's actually measured it.
thanks!
