Pulley diameters?

[jeffbaze]

Does any one happen to know the pulley diameters for the Mark VIII'S I need to figure out the ratio's for a scan tool I am using

I know the oem crank pulley was 6-3/4" and the alternator pulley was 2-5/8".

I now have the steeda crank pulley which is 5-1/4" and an overdrive alternator pulley which is 1-7/8".

I forget the waterpump pulley diameter but I know the stock pulley is the same as the electric water pump dummy pulley.

Does that help?

Actually that does, that will save me a little time with the measuring tape
thanks
