I have a recently rebuilt 56 235 engine in my 3600. Runs well and idles fine. For whatever reason I noticed the dist. wobbling in the motor. First I thought the shaft was bent but it isn't. The whole dist moves quite a lot in the block. It should have just a slip fit right? My only other car with a dist was an MG. IT WAS A TIGHT FIT. Let me know what you all think. Thanks Sharon
