Default th350 convertor ?

Im putting a th350 into an 98 ls1 camaro. I bought the Hughes crank sleeve to fit the th350 convertor to the ls1 flexplate. I have no play in the convertor. It will turn put in wont move foward or back. I have heard you need an 1/8th of play in the convertor. Is this true? If so what do I need to do to get it to work?

Thanks,
Ricky

You do need that and I suspect the converter is still not fully seated in the pump .

don't you have to change the flex plate to accept the small bolt pattern of the th350?

The hughes adapter may not be fully seated in the rear of the crank. I had to use a rubber mallet to fully bottom it out. The adapter is a loose fit on the convertor but a tight fit in the crank.
If your adpater is fully seated, then your converter is not all thw way, OR you have convertor that was built for a TH350/400 to LS1 already and do not need the adapter.

Hope this helps,
Rick

Not if you have a 98 flexplate. Even the newer ones can be "wobbled" out, but is not recommended.
