Complete 350/350 with A/C & PS

[ls1nova71]

I did a quick search but didn't find what I was looking for. Trying to get a ballpark figure for what the engine and trans in my truck is worth. It's the original 350 with a 350 turbo, has all the A/C brackets, and power steering pump and brackets, and also has the tall oil filler tube. Has a rebuilt Quadrajet, and a new water pump and it runs great, but just doesn't get the kind of gas mileage I would like! The down side is it leaks. I assume it's been rebuilt as it will peg the oil pressure gauge when cold, so I'm thinking it's got a high volum oil pump in it.

Would it be better to sell all the brackets seperately, and if so, what are they worth?

Thanks for any input.
