I had a short tube on the last distributor and i flattened the tang on both sides a little to make it a comfortable fit in the slot.
Going back to my original question, could the bush possibly cause a problem.

---

Not by much at all... if the bushing is worn you
still wont get rotational play, you would get the
shaft moving side to side... if the chain is tight
then its down to the cam walking back and forth,
the intermediate shaft moving up and down or a dist
problem (binding then going free)

yes

if its out of round and there is play in it, oversized to the shaft

it gave me problems


repaced it and with locked timming *35 needed to get a msd start retard box

Did you replace it with the motor together, i presume it's pump off and tap it out with a rod from underside and long nose pliers to pull it out the top.
When i fitted the MSD dist, i didn't fit the rubber hose back on and the car lost 3-5 mph at the weekend.
The only other changes since the previous meeting are a larger rad and i've changed the electric fan for a viscous fan.

If you want to change the bushing while the engine
is still together, make up a J on a slide hammer to
pull it out (go down through the center of it)

What a great idea, thanks Mr P I knew i could rely on you.
I want to change the bush but i'm also going to buy a dist collar and maybe look into another bronze drive.
How would i know if i had cam walk, cam is a crane roller.

Take a big screwdriver and in the dist hole move the
cam back and forth... I think the spec is like .010-.015
but I'm not sure on that.... you know what that looks
like so if it moves a fair bit you need to correct, but
that turns the intermediate shaft more or less as
the cam moves fore and aft

YES

I did it with the moter in the car

GOT A LONG 5/8 BOLT .... 7/16 THREAD AND THREADED IT IN THE BUSHING AND PRYED IT OUT SLOWLY
HAD THE MANIFOLD OFF AND VALLY PLATE TOO

this was when I went to 12.5 comp and 613/276 cam upgraded the from 9.1 528 solid


timming was skattering all over ,when I changed the bushing it was steady but hard to start and put a retard box in for stating the moter over easy

---

i would think the distrebutor could help hold the intermediat shaft in line.the intermediat shaft must have been like throwing a hotdog down the hallway. anything can happin i guess.

I used to have the dual line external oiling system and because of drain back i would always be priming it, this may have caused the bush to wear.

Did your erratic timing lose you much power.
