Has anyone seen this before?

You need to place that pulley onto the balancer and see if the part that fits into the balancer is tight or if it moves too much. That part needs to be centered and the three bolts are not enough to do that, it has a hub for a reason.
I've read that the balancer is thicker on the V8 and you have to use a V8 pulley anyway.
"had to get a V8 specific crankshaft pulley as the V8 uses a different thickness harmonic balancer and consequently different pulley". See post #6.
