Andy F. , YELLOW ROSE , DO U KNOW OF A "SINGLE" BELT WATER PUMP PULLEY THAT IS SMALLER THAN THE APPROXIMATE 7'' big block pulley ?? I`d like to speed my water pump up a hair w/o changing the stock alt. and crank pulleys.
thanks in advance--------------bob
(can`t seem to keep my fingers off the cap button) disregard them---------
 
I have a bb waterpump pulley that is 5 3/8" inside the groove diameter and the offset is 2 3/8" from the mounting face to the center of the groove . Is this any help ? Tom

I was thinking about that too. I went to junkyard and bought a bunch of used pulleys laying loose back when I built my 406sbc, but haven`t got any left now, probly trashed them when I came home!
