The pumps vary in length even when stock, shims can be added this page explains more about it. I'm no expert but hope this helps you Mitch :D

I'm thinking Mercury Mitch's problem is that the diameter of one or both pulleys (crank and waterpump) is too large - not a belt alignment issue ?

Can you post a photo of the pulleys fitted if possible and let us know the pulley diameters ?

Then I will check my 283 and let you know

Had similar issue some months back when setting the 350 that came in with the 49 pick up for aircon and power steering . I tried using crank pulleys and water pump pulleys and power steer pump from my spare 350 . Aside to the long/short water pump issue, I did find different diameter pulleys. Water pump pulley from memory. All good now I had to buy in a dual p/s pump pulley from the US.though.

they look like the pulleys I had got rid of them std chev ones went straight on was nothing to do with my water pump Mitch
I tried them on my crate spare motor as well same thing if it was pump it would mean the shaft is too low
my pulleys came on an orange card from memory and RPC or rpm was brand name

this is ones I got
