You will need a spacer, flywheel and different bolts. The spacer bolts between the crank and the flywheel (hence the need for longer bolts) and you need a new flywheel to restore the alignment between the ring gear and the starter. Let me see if I can dig up those PN`s.

i thought all you needed was to get a converter with the correct hub/snout for an ls1 when ordering? can anyone confirm this?
i personally know a guy running an ls1 with a th400 and he's not using a spacer/adapter of any kind. he just had to order his converter to be used with an ls1 and that was it.
i don't know what he did for a flexplate, but TCI makes a stronger than factory one that most guys are using with their th350/400 swaps.

I believe that the spacing for the 3 bolts that bolt the convertor to the flexplate is the same, but I cannot guarantee that yet as I have not physically checked it. In another post I read that you need a 1998 flywheel and that the 1999 and later have a 2mm smaller diameter bolt circle. That does not make sense to me because I bolted a 4l60e from a 1998 camaro to a flywheel for a 2001 tahoe. I have a 6.0L flywheel and spacer sitting so i could give you the dimensions if you want, but all my th350`s and 400`s are buried in the back of the garage so I have not tried to actually bolt one up.
