    Everybody knows when building a engine all of the little parts that need to be put on soon add upAfter finding out that my pull set up was out of alignment I was looking around at spacesMost spaces are around $35 and moreI found this one and the build quality is fantasticJust measure the crank pulley all of the way against the harmonic balance and then get a level and a line the water pump pulley with crank pulley and take a measurement with Vernia calipersMine was .25 so I was able to find the correct spacerThank you Speedway for not gouging me on the price

    When going for a 327 to a 350 the harmonic balancer pulley did not light up this fixed the problem
