What the heck is up with 8-3/4" rearends?

Just like a seller here that just posted a 600 Holley for $175. The one I bought for $100 must now be worth $175.

This comment is funny!I have to assume this was directed towards my carb ads. I just sold it in less than 24 hours of listing it. This carb is a $325.00 carb on Summit and I had it priced at $175.00.This thing was only used a handful of times and looked like brand new. I'm not seeing the issue?????????????????????????????????????????????????????????????????
