Building an older LQ4...Have some questions...
Well I have a 2000 model LQ4 at the machine shop as we speak, its having to go 60 over, so that will make it a 376 correct? I have read alot about the older cranks being longer than the newer ones, and id have to change it out to a 02-up so that i could bolt a 4l60e behind it...question is, im wanting to do a th350 swap behind it, so could i use the longer crank to eliminate having the spacer for the th350/400 swap? thanks guys

Yes the longer crank is what you want for a th350 you will just need a different flex plate. Neil Chance makes an excellent converter for LS1 to TH350-400 trans and its not very expensive.
