LS 6.0/TKO ?'s

[NvrDun71]

Planning on running a TKO 600 behind an iron block 6.0 in my 71' Nova. Was curious of what you guys are running for a bellhousing, clutch, & flywheel w/ an LS/TKO? I would like to run a GM ls7 clutch, flywheel, and pilot bearing but haven't been able to get a clear answer on if this will work and what bellhousing I will need to run? I have a new CC5speed "621" aluminum bell I was planning to use on another motor, but am unsure if it will clear the ls7 clutch and work w/out probs w/ the 6.0? Will be running mechanical clutch linkage also..... Did a search and didn't turn up much info, someone enlighten me!
