Small block 727 questions

Sigh... I used to know all this stuff...

I just found a 727 behind a 360 in a pick-up truck. It had a -489 case 8 3/4 out back, with 2.92 gears. I don't know if either of those would be an indicator that the trans has beefier guts in it.

What's a small block 727 go for these days? Money is really tight, and if I can pull this thing out and flip it for a little extra project money, I'd be thrilled.

What're they worth, and with the availability of 518s with Overdrive, does anyone mess with the basic 3 speeds anymore?

Thanks,
