Anyone run without one. What is the purpose off the pilot to go into the back of the crank, if the converter is help tight on the flexplate what would it hurt?

The converter is not made to be supported by the flex plate you will get vibration,eventual flex plate failure and possible pump damage the back of the crank is the support and center for the converter the flex plate does just that flexes and will not stay true .

You can get a custom converter with an ls1 pilot as well.

Yes those are available but under no circumstance run the converter with only flexplate as support

Ok thanks, How about if i run a spacer between trans and engine? it works perfect if i could do that.

Not to sure about that either since the trans depends on the dowel pins for supports , Alot of people think the bolts are what keep it from twisting on the block but in reality all they do is hold it against the block , The dowel pins keep it centered and from twisting

You can bend the flexplate by hand, imagine how much flex it would encounter with no center support. For the money, it's extremely cheap insurance. I think I paind mayeb $180-$190 total for hughes flexplate and adapter through summit. Just my .02

Ithink i will just get a converter that will work without the spacer.

Any idea why my converter is binding in the gm spacer? i have to use a washer between trans and block and it will work, I am prettty sure my converter is all the way in.

i have heard that some people that use the gm spacer on the front side of the flex plate sometimes need to mill about .100" off the spacer, i have not ran into this issue

what flex plate are you using?
