Jim, been out on vacation so havent read my emails lately. I took the
entire distributor apart, so all I have is a housing with two dist shaft
bushings and a shaft with the cam block/advance mechanism in place.
With the dist in a vise, I used a dial indicator to measure the
side-to-side play on one of the cam flats, which was 0.0035". If I take
off the cam block and measure the shaft side-to-side play by itself I
get 0.0025".

Listers, still in engine rebuild land. My distributor shaft has about
.0025" of runout. Is that alot, or should I think about replacing the
distributor drive shaft bushings? I dont see a spec in any of the major
books, but I would guess that runout translates into a change in dwell,
and hence ignition timing. Thanks and happy holidays. My engine comes
back from the shop today, I basically gave him my wallet and said here,
try not to take all of it!
