As a guy that's had a couple of big bangs I can tell you that almost all body external modifications just plain will not work.
Those approved housings work because they are clearanced super close to the flywheel. As 220mph commented, a smaller clutch can get loose and get through even a approved housing if it has room to move up or down or around in the housing. By making things tight, the thinking goes, a explosion will turn on itself and self destruct. Any extra room in the housing will let blown parts build up kinitic energy in a housing, and you risk those parts not turning on itself, instead going straight up possibly. And those parts could go through even thick steel. That's why scattershields are made of moderatly thin steel and how they work. Adding plating to a tunnel in lew of a scattershield is a very, very bad idea IMHO. And so says my NHRA tech inspector. Don't give that flywheel room to move around, buy a scattershield or approved housing. A automatic with a converter is another story and for another thread. Hint; It has to do with liquids.
