We all like racing a lot or we wouldn't even be on here, but I think the main reason a S/SS guy wouldn't want to attend foot brake and bracket races very often--no matter how good the payout is-- is that he doesn't want to put extra wear and tear on the expensive, specific, and likely very hard-to-find parts and pieces that allow him to be competitive in S/SS in the first place. It would almost require a second dedicated car to be used for bracket racing only. Otherwise, you'd be a real busy guy doing constant maintenance.
If you had a zipper on the Stocker engine bay and could slide a mildly modified SBC and plain jane Turbo 350 in and out of your easy-to-work-on '68 Camaro in the span of a couple hours every Tuesday night when you wanted to go run a big-money bracket race for the weekend, yeah, they'd be more apt to do it. But they don't.
