This is an excellent post, gives the phrase "plan Ahead" some real meaning. Building an engine is different than putting one together. In this case I just cut the pulley to fit, but sometimes that doesn't work, but I've had no trouble with that solution. However. I prefer to use the GM harmonic balancer, bored for a press fit to the crank then add or make a pulley. But planning this is the important part of building an engome.
