I spoke to the seller of the ly6/4l80 package and he dropped down to $4k. Although he seemed like a nice guy and I wanted to help him unload his project since he helped me out with the 823 single head I needed, I'm taking the advice of you guys and working on piecing together the rest of my engine and drivetrain package for the Blazer.
Having talked with a guy named Shawn (RetroLS) in Atlanta who sells LS engines, I gave him a call to inquire about a transmission and the accessories my engine was missing. He happened to have a few things on the shelf. He quoted me the following:
$900 - 6L80e (AWD with less than 30,000 miles) He told me the AWD 6L80e would mate up to the NP205 that came behind the TH400 (6-bolt round style as opposed to race track bolt pattern). Still trying to research this...but he said he knew of a lot of tube chassis trail buggies running this combo with either a NP205 or Atlas transfer case. I currently have old style NP205 but am considering a LoMax 3:1 NP205 Gears/Case kit that has both bolt patterns and has 3:1 gear ratio.

All of the accessories quoted below are of an 2010 Escalade with 8500 miles. He sold short block and was left with a pile of parts nearly new parts.
$220 - full harness
$100 - ECM
$80 - Pedal
$75 - PS Bracket & pump
$75 - Water pump
$80 - Escalade Alternator (high amp)
$200 - Intake with injectors and fuel rails with throttle body
$125 - Coil packs with plug wires
$65 - MAF
Comments and Recommendations welcome! I know I've got to figure out the harness and programming of the TCM in the 6l80e but I think this harness and ECM that is coming off of a 6.2L/6L80e setup should work? Learning as I go.....kind of!
