Fluid dampener pulley alignment question
Little late to the party, but there's a bolt on option. March performance 10151 crank pulley has the correct offset for the early fluidampr/SM/CAT/etc. It doesn't require any shimming, but it's single groove only, so WP/ALT only.
You can also run the 69 and earlier crank pulley with the 70+ water pump, but I think that still requires a shimming both accessories.
