Stage 2 engine for sale in TX

[BadJack]

I recently lost a good friend who was a Buick collector. Among tons of parts and parts cars he has a stage 2 engine that I need to sell for his wife.

Unfortunately I don’t know anything about it. He had been planning to put it in a 87 T Type that he had but never got to it.

The short block is complete with crank and pistons/rods. It has aluminum heads and intake. Headers and turbo.

I don’t have a clue what this is worth. Anyone care to give me some direction?

Thanks.
