LS1/T56 combo

[67pro-street]

Hey everyone,

I've been storing a LS1/T56 combo in my shop for a friend of mine who doesn't have a dry place to store it otherwise. He bought it from a junker car about 10 years ago for a project that never happened. I think it had around 20k miles on it. He previously had the engine stored at his dad's house, but it was stored outside underneath a tarp. All the ports and holes were covered, but it was outside. The condition of the inside and cylinders are unknown (surface rust and what not) and the outside aluminum is a bit white from corrosion and whatnot. I found previous posts from people asking what this combo is worth, but they were a few years old, so I am wondering if anyone knows what this combo might be worth nowadays. He does have all the original front drive accessories and the original wiring harness.

Thanks!
Aman
