OK....Took the motor out and put it back in. Everything was fine before. When I put it back in and bolted everything up, the flywheel is rubbing the top corner of the Bell Housing in about 2 different spots (on the flywheel) during a complete turn over. My question is, what could have caused or be causing this, and will it simply quit when I run the engine? Keep in mind that I can turn the engine over by hand and that the flywheel does not look warped at all. Please HELP!!!!

Ain't no way Bubba! Something ain't buttoned up right. Somewhere, somehow!
Did you do ANYTHING different? Change anything? Different bell housing? did you drop the bell housing and put a big dent in it?

Tom's right... can't happen unless something didn't go back together the way it came apart or you changed something. Is it a flywheel or flexplate(manual or auto)?

BTW...DON'T fire it up 'til you get this figured out. It won't go away by itself.

Are you properly alinged in the pegs. That sounds impossible to have the flywheel or flexpalte touch the housing. If it was misalinged I don't undaerstand how you could of lined up the torque converter or insert the tranny into the pilot??????

Is it manual or auto? If auto, the flex plate could be bent, possible when the motor was being installed (have done it before) If it's manual, it could be the clutch cover rubbing. Is it the original clutch cover? or flex plate?
PS check the dowel pins were not pushed back into the block when it was reinstalled

It is an auto.

Also, Is it possible the tranny could be in a bind? The car was jacked up a little unlevel when the motor was installed. Could taking the tranny lose and putting it back in help? Nothing was changed here.

I had this happen before, when running it made so much noise it sounded like a rod banging. while I was looking around the engine trying to figure it out, it stopped completely, dont know if it "self clearanced" itself or what, but didnt have any problems. I figure the flexplate got knocked when the engine went in, but it didnt cause any problems and I ran it dirt track racing at high rpms. the other time I had this happen was with a v8 vega I had, somehow I got a th350 trans which had a physically smaller bellhousing and would only accept the smaller chevy flexplate. But in this case the flexplate was touching all the way around the upper bellhousing and there was no sense even trying to start the engine. Dont know what the trans came from originally, but because it was small it fit great in the vega..

Is theflexplate on backwards? the ring gear would protrude outwardly if it was.
