I have an ATI flexplate on my new engine.
Its a "swap"plate meaning it has 157 teeth ,
but a 50 oz. balance.The plates center hub looks very thick to me, and when I put the engine in my car the converter has NO end play like it should. The converter IS fully seated in the trans(I know `cause I pulled the engine back out just to make sure!)It "dropped" 3 times when I re-installed it. I plan to contact ATI about this ,but I was wondering if any of you have had the same problem before? Could it be that I`m supposed to use some kind of thicker "racing"
plate that goes between the engine and the transmission??

Mav, it really sounds as if you are NOT getting the converter all the way in the trans. We use the Reactor billet flywheels exclusively and they are the thickest in the industry. Thicker than the ATI units. Our convert uses the 50 oz version. We have no problems with any of them.
I would pull the trans once more and keep spinning the converter as you are pushing it in until it falls back at least 3/4 of an inch. The it should draw up to your ATI flex plate. Good luck.

Thanks for the response Alex.I will move the engine out of the way again and totally remove the converter from the trans ,then re-install it. Also it occured to me that
If they did make a thicker plate to install between the engine and trans, It would cause some interesting starter engagement issues!
(now smacking forehead :rolleyes).

Take a straight edge and place it across the front of the bellhousing with the convertor inplace. The convertor should be within the bellhousing the distance that the flexplate is from the back of the block plus 1/4" or so.

By chance, did you leave the engine block plate off?
