It takes a bit of creative machining, but I've built up a few distributors with a Torrington needle bearing at the top of the housing for a zero-wobble top end. It's surprising how inaccurate some distributors can get, either from wear or manufacturing tolerances. Jerry

Handy Andy My local 55 year junkyard where they are true junkyard dogs,test HEI's this way-put 12v jumper cables on it handle it like a hot potatoe spin it if it pops and cracks is good. Best part is they turn you loose in the yard,covers about 120 acres,amix of 30's to current vehicles.
Joe H: I'll shoot for that .010" to .020" range for end play. Do you have a source that you can share for those bushings? I'll have to look these distributors over closely. Hopefully, I won't need to replace the bushings. I'm aware of the alignment mark and the rotor orientation. Good reminder, thanks!
Jerry: The needle bearing sounds interesting. However, the bushings should suffice for my purposes.
fixite7: You are very fortunate to have an auto salvage yard that not only has the parts you need, but they turn you loose too! The pick-n-pull salvage yards are long gone in my neck of the woods here in Iowa, or paradise as 52Carl fondly refers to Iowa.........right Carl? I suppose turning people loose in a salvage yard is a 'big liability issue' these days, or so I've been told.

Joe H Hey say that again about align the dot with the pointer on the rotor !! Never heard of that yet,My HEI's mostly have the gear turned over then drill the roll pin hole...at random,shim and assemble put it in maybe shim with gaskets. Been a while cause mine are all running,winch truck set 5 years fired right up.
On the gear, there is normally a dot machined in to the side, this aligns with the rotor pointer. It aids the installer when aligning the oil pump drive shaft to the distributor gear drive. ( 99% of what I work on is Pontiac stuff, so this maybe related to them ) If you know where the dot and rotor are, you can turn the oil pump drive so they mess together with out rotating the engine or taking multiple stabs at it.
I finally got some garage time in this afternoon. A local farm store had those 1/2" machinery bushings, so I filed them a bit to get the needed clearance. There are two shims placed above the distributor gear which leaves me with 0.010" of distributor shaft end play. This quite an improvement from the 0.125" that I started with........
