Ford 302/351W Distributor Gear Height Addendum MSD Pro BIllet

MSD calls for 3.996" - 4.005" from collar ( location above O-ring) with shaft pushed in. Ford says 4.028-4.032 with pulled out. This distributor has a .023 amount of end play. I called MSD and their response was as long as your'e within our range it should be fine. The only issue with that comes down to your block... Obviously most people use used/reconditioned iron blocks that could have varying heights of wear on that block support. Ford calls for the gear to rest on the block support and still have enough to go down... Obviously over time this will wear but my concern is if you have it too high while the cam wants to pull it low the gear pattern could be off or the cam could bring the shaft out of the distributor... So In my experience I would say, know what MSD wants but set the height based on your block. Fords advice is based on being the manufacturer of not only the distributor but the block itself, MSD / warranty is giving a general range. but for $400+ and the rest of the engine it's something I got meticulous with.
