Why are there so few blown small blocks?

The kits are available, although that could be a large part of it. They are not cheep.

I could buy a set of mirror image NRE turbos for about half the cost. (My buddy is a dealer for NRE).

I've done a lot of searching and it looks like our of everyone on this site theres three folks with blow small blocks and about three hundred with turbo small blocks.

I realize they dont make the crazy power numbers that twin turbo can but our blocks cant hold 1,000+ HP any way.

I'm just very surprised at how few there actually are. Come to think of it. I've never even seen one in person. I've seen a few blown hemis and 440s but zero small blocks.
