I'll say it again, the gen 1 sbc is going the way of the flat head and will be looked at in a similar way soon. There will always be enthusiasts into them though.
The sealing methods, crossbolted mains, light weight and superior head flow of the LS are just too great to overcome. The ports in the SB2's in Nascar look more like an LS7 than a Gen 1.
Also price out a EFI'd gen 1 compared to an LS, you'll be suprised.
