Just got my engine back and everything went smooth until i had to put the pulleys on. Thats when i noticed that when they rebuilt it they put a new balancer on and switched from my 3 bolt balancer to a 4 bolt balancer. I spent 2 1/2 days looking for pulleys. I finally found a pair that fit, but i am worried about cavatation on the water pump pulley because it is significantly smaller than stock. Does anyone know where i can get a crank pulley(pulley set) that will get the water pump pulley back to the proper size?
