How long had the gear been installled on that particular distributor? Contact MSD and get the required measurement for installing subsequent gear. The thrust face of the gear is pulled down against the thrust surface that is machined in the block where bottom of the distributor shaft slips over the hex shaft for the pump. If it does not rest on the surface while installed the gears will not mesh properly. If the shear pin is shearing there are forces preventing the shaft from turning once engaged. As you have stated check the bushing inside the distributor and check the pump. It is possible to have a small piece of metal that has gotten on the outside of the gerotor inside the pump. This situation will continue until you actually find what is preventing the shaft from turning.
The decking of the block with a 289/302/351 does not affect the meshing of the gears as stated above (sorry Chappy), The installed manifold hieght has no impact on the distributor fit.
