Will this pulley fit the harmonic balancer fron a 94 gmc 350? I am using a 350 from a 94 GMC in a 51 GMC and going from serpentine to v-belt. I would like to use the existing harmonic balancer if possible.

In most cases pulley number 91015478 will work on the later years such as your 94 with a 350 and serpentine belt system to switch to V belts. Occasionally the shoulder on the center hole does not match the balancer in which case it could be ground down for a flush fit against the balancer. This pulley is for the long water pump and also available for the short pump if needed. Shimming of the water pump or lower pulley for proper belt alignment may be required.
