trans question?

[High ho silverado]

I know this has been discussed in length and I have looked through several threads on here and other sites but can't quit get an answer. I did a 6.0 swap and used a 98 trans from a 5.7sbc, I ordered a ls bellhousing and changed it and my 6.0 had a spacer and 80e flexplate that I ground out the holes for, but when I put it all together it seemed like the converter had to pull forward a lot, jus seems like its to far forward out of the pump now, can the bellhousings have a different dish to them? I don't want to start it and ruin a new trans and converter. If anyone has any info please let me know, if I don't have to take the trans back out I don't want to. Thanks
