Overdrive Pulley Set?

Do u have a depth measurement of each pulley. What are the sizes u have now? Cast iron or alum w/p? May be able to change just the bottom one also. How much clearance between them? Kim

Its the later aluminum w/p.

I've tried finding just a larger crank pulley or a smaller water pump pulley, and no dice.

I'll take a couple photos and do some measuring and let you know.
