[AMC-List] 3 bolt vs 4 bolt

["Jim Boone" <fljab@xxxxxxxxxxx>]

I have 2 complete sets of pulleys (to support AC) for a 4 bolt balancer.  My 
 '70 390 is a 3 bolt.  Can a 4 bolt balancer be physically put in place of 
the 3 bolt balancer?

If the physical mounting surface is the same, then that should work, 
balancing issues aside.  The balancing could be dealt with during rebuild.  
Any other options?

I have had no luck finding a 3 groove, 3 bolt lower pulley.  From talking to 
different people, I'm not sure they made them.  Was AC driven off another 
accessory, like the alternator or water pump, up through 1970?

Thanks,
