What's this worth? (please)

Not sure if this is the right place for it but:

I'm in the midst’s of an LT1 swap into my '86 Iroc, and someone has shown an interest in buying my old 305TPI and tranny. It has ~94,000 on the clock, runs good, but uses about a quart of oil every 3,000. I want to know what a fair price would be for the engine/tranny combo. I can't imagine it's worth much, but every little bit helps for finishing my swap!

The whole TPI intake is worth more then the 305 under it. I would sell that seperately, I have seen them for $500. The 305 get what you can without the TPI and 700r4 the same deal. The TPI is the Big buck item, not the other junk.

Thanks for the awesome advice, I'll definately look into that
