Question of moment!

It may have a pulley bolted on the front of the damper if so remove the outer pulley (3 small bolts) and install the large bolt in the end of the crank with no washer to protect the threads in the end of the crank then you can use a standard harmonic balancer puller to remove it. My understanding is small and big blocks have the same size bolt that you need for a slant 6 for some reason Chrysler got cheap on slants and did not install one at the factory.
