anybody had a serious bell housing run out and what were the effects?
Funny, I had the same problem when I put mine back together. I took the clutch and pressure plate back to Summit for an exchange. I also replaced the flywheel and pressure plate bolts and made sure that they were torqued to the proper spec. It still vibrated like a son of a bitch. My buddy suggested that it might be the flywheel even though it was re-surfaced at a local reputable shop. I reluctantly bought another flywheel and the vibration went away. I don't know?I have a friend with a 383 4spd super b we rebuilt the engine (stock) and everything was running smooth, in fact I was surprised it was so smooth. he took the tranny and bell housing out to repair a trans leak and now it vibrates so bad I wouldn't drive it. got me stumped!
this car had the stock flywheel resurfaced and initially drove good. the original bell housing got broke so another '69 bell was found and used during first running. something went goofy when the trans and bell were taken off and then reinstalled.Funny, I had the same problem when I put mine back together.

An automatic trans case should be checked too, especially if you plan on racing the car.I know I’m old, but I never heard of this problem 40+yrs ago; course I’m into 727’s. There surely weren’t offset dowels long ago? (are we talking QC in this day and age?)
I've pulled stuff apart and found plenty of crud between the mounting faces and these things were not that old at the time. There was always someone modifying newer cars back then just like now but back then, there were way more shade tree/junk yard builders. Makes ya wonder sometimes lol. My first rent house had an oversized 1 car garage but the floor was so cracked up that there was no way to make an engine crane roll so a tree was used to pull out a couple of engines until we got the garage braced up good enough to hang a chain fall. Found out pretty fast not to look up to make sure the limb was going to hold without wearing some kind of eye protection!this car had the stock flywheel resurfaced and initially drove good. the original bell housing got broke so another '69 bell was found and used during first running. something went goofy when the trans and bell were taken off and then reinstalled.
When does the vibration come on?this poor old car has been thru some crap thru the years. the bell housing this fellow bought to replace the original may have had issues. the thing vibrates terrible as it's revved up. any ideas are appreciated.
from off idle and gets worse as rpm is raised.When does the vibration come on?
