harmonic balancer

kick said

Looking for recommendations on my stockish 71 340 build. I don’t mind spending a few bucks but it must put the pulley in the stock location. I was looking at ati but I can’t verify if they have one that puts the pulley in the stock location. The pro race-pro sport looks like it would fit the bill but then I see some issues with those online.

Just going through this getting ready to rebuild a 69 340, hopefully after Christmas. There are basically 4 different internally balanced harmonic balancers: 65 down 273 and poly 318; 66-69 273, 318, and 340; 70-71 318 and 340 (drivers side timing marks); and 72 340 and 72 and up 318 (symmetric pulley bolt pattern). I am not counting cast crank weighted or 318 auto trans dampers. I have a NOS 65 down, an original 66 273 Commando, rebuilt 66-69 340, Fluid damper, BHJ 66-69 340 E-Performance damper. The plan is to find true TDC on this short block then check timing marks and pulley alignment on all the dampers with a cast iron water pump.
