Hotchkis lowering springs and BBC

Does anyone have a BBC with the Hotchkis lowering springs? I'm just trying to see how low the car would actually sit in the front with these springs and an iron headed BBC.

I have them on my car with an aluminum headed small block and it sits pretty low. I have 165R15's and the front fender lip is 24 inches from the ground measured at the spindle point.
