I saw the price on the WZ block. Being somewhat new to the purchase of Pontiac blocks, is this what a WZ is worth?

I have a 68 YT 400 block with #16 heads that I am getting built up for my 50th birthday. Is this a valuable block as well? I bought it with the heads, crank, pistons, rods, well, most everything for around $450 about 3-4 years ago. It was magnafluxed with no cracks as well.

Have they gone up in price lately?

I ask not to dispute your price, but to gauge what my parts are worth.
