Ls2 or Ls3?

[cpd004]

For primarily a street car, I was offered a complete 56,000 mile 2005 Ls2 and 4L60e out of a GTO for $5800. The other option is an Ls3 out of a Corvette with 10,000 for $6000. Both are complete with harness and accessories, but the GTO comes with the trans. The Vette motor does not, so I'd need to source something that doesn't require tunnel mods (no 6L80e). I'd imagine it'd take another couple grand for a trans for the ls3. Save some money or ??? Opinions?
