3.6 in A-body

I'm just starting my research, and am seeing 8 3/4" at $2k-$3500 all day long - which makes me long for the '80's when the junkyards were full of them! The few 8 1/4" I've seen were pushing $1k as well. My Dad always said 'asking ain't getting', so I don't know what they're actually selling for. I'm looking at options right now.
