Larry,
  I machined down the original pulley, and fitted an alluminum outer ring to it 
to match the size Kass called for in his spit prep manual.  That seems to work 
just fine for me, you may be able to do a similar thing on yours.

Since I put the crossflow radiator in my TR3, I have no overheating

with a water pump that's pumping against an almost closed thermostat. 
I'd like to reduce the water pump speed by about 30 to 40%. That means 
I need either a bigger water pump pulley or a smaller crankshaft 
pulley. I've got one of the new narrow belt pulley and harmonic balance 
kits. It's got an even bigger crankshaft pulley than my current one. 
I could probably make a hub for a pulley if I could find a pulley & 
harmonic balancer to bolt to it. I've also thought about an electric 
water pump, but I'm not sure it would be legal in my race group. Any 
suggestions and advice would be appreciated.
