Al .
I think your first notion is the best one ........A blow proof bell housing and high rpm clutch are at least what you should do .
My step dad had his right leg taken clean off just below the knee by a big chunk of shattered flywheel. The engine was maybe turning 3000.........he went to the hospital in a helicopter or he probably would be dead.....and no.......they couldnt get it back on.
Now think about the relative location of your flywheel to yourself when seated in your car...!!
These are thinly disguised race cars and most of us are running vintage hardware that is a bit more prone to snap than it once was.
I dont mean to sound preachy , but I've seen the aftermath and I wouldn't want to be "the one"
good luck
