Which LS to buy?

Question for the experienced LS swappers...

There are a couple LS engines that I've seen available and I wanted to get feedback on which one would most valuable.

Option 1: LS1/4L60 out of a 99 Trans Am with 120k miles (7k/year). 243 heads, cam kit with pushrods, lingenfelter intake and 4L60 has a new SS3600 Yank converter. Made 383 rwhp/380 rwtq. List price $3900 seller open to offers.

Option 2: LS2/4L70E out of an 09 Trailblazer SS with 28k miles. Vehicle was wrecked and both removed. Stock specs. List price $6500, not sure how willing they are to negotiate.

Option 3: Neither of these is right and I need to keep looking. Please make suggestions for potential sources.

As far as I know all options are complete with harness and accessories. I'm planning to use the swap in a 69 K5 Blazer that needs to be a Socal daily driver. What are your thoughts?
