play in distributor shaft

[nickmav70]

im having some wierd timing issues with my efi 5.0... my questions is could i have timing issues from play in the distibutor shaft? how much should it have? should i be able to move the shaft up and down with it installed into the engine? how do i measure the thrust on it and what are the specs?

if anyone can answer any of these questions it would be great


thanks

Whats the distance from the flange (where it sits on the block) and the top of the gear? You can make shims to take care of the slop if needed...

There is a spec for up-down movement of the shaft in the body, and then you can shim the dist in the engine some. Note the gear orientation tends to pull the dist gear down, iirc.

Dont have the numbers handy. I would not think this to be a common problem though.

end play is .024" - .035"
