It's a double edged sword. Higher values do make it harder to buy a wagon, but if you already have one it's great. That is super clean, low miles, loaded, and one of the rarest years. I think the B and D LT1 cars will be like the tri 5 Chevys
I have had both and far prefer the tow package. The 2.93 gear and posi far outweigh the mechanical fan, which i don't mind. There is a quite noticeable difference in acceleration. Even if you do a gear swap, you can avoid buying a new posi carrier, which is way more expensive than the mechanical fan delete.
