Does anyone know the factory sizes of the water pump pulley and the crankshaft pulley ?

I took mine off 10 years ago and have no idea what I did with them. I now have the March Preformances on for the power amp but I have all kind of problems with the alternator drop off at idle and in gear.
So I need to know if the water pump is same size or not. I know crankshaft pulley is different ..

Thanks ,

V-belt, serpentine, or '86 combo?

 

It is a 305 V-8 Serpentine

 

I finally found my factory pulleys......thanks for looking ronnjonn

 

The thing is, I don't have the serpentine, or I would have posted the measurements for you. I'm glad you found some. I hope they work for you.
I'm feeling disappointed that noone else could be bothered to measure theirs for you, as there's no shortage of members who could have.

 

Yeah... I went a couple days looking for my pulleys. The problem was I took them off the car 14 years ago and can you remember what you did 14 years ago ? Hopefully by putting the factory crankshaft pulley back on it will solve my problem.

Thanks again for trying to help.
