Looking around eBay I found this engine. Its auction number 170439421248
The guy says its a 93, but you can clearly see "506" cast in above the valley. Its pretty nasty so you can't see the valley. I know my old 506 block did not have the 506 on the valley sides, but my Optimizer does. I emailed the guy to ask him about the diamonds in the valley and he said he didn't see them, but who knows if he even looked. Might be worth checking out if you are in Indiana.
