Question on pricing

Ok, for those of you in the know on values of certain parts, I'm looking to set asking price on an engine, an a rear end.

The engine is a 70 340, with Edelbrock air gap manifold, holley 4bbl(750 I think), but I also have the original heavy 4bbl manifold...and the exhaust manifolds. The engine ran when I pulled it from my now gone 64 Barracuda, ..the cam shows pitting. Prob needs a good going over, but it's a good starting point.

The Diff is an 8-3/4, 3.23 sure grip, mancini axles. Not sure what case, but before I put the ad up, I'll get pics and all.

Any help would be deeply appreciated
