I see the snout on the Eagle crank is about 1.75" while a stock 440 crank is around 2.5".

I agree that old design Fluidamper doesn't allow the stock pullies to line up (no recess for the pulley).

I am wondering about your crank snout info.
Is the measurement in this pic what you are talking about?
1.767" plus the crank sprocket thickness of 0.78" = 2.55"?
