Harmonic balancer 63 340HP

[Richard S.]

I would appreciate if someone can tell me the offset distance between the lower front surface of the stock water pump and the stock front edge of the stock harmonic balancer. The engine is a 340HP 327 (63 vett) therefore it has the larger high performance harmonic balancer. Are they in line or offset in or out relative to the front surface of the water pump. My view is from the driver side with no alternator in place.

I don't have any pictures handy but the pulley on the water pump has to line up with the pulley on the harmonic balancer to make the alternator and tensioner belts align.

Yes I know that but I am interested in the offset between the water pump front surface and the harmonic balancer front surface. Even without a measurement if you are able to look at the two surfaces installed in the car do you see an offset one way or another?

There is a set up dimension for the water pump mounting surface to the round mounting impeller flange in the maintenance manuals.
