aluminum scattershield?

most muscle cars came stock with an aluminum bellhousing from factory, if the cluthc were to fail in a bad way (like an explosion!) its cast aluminum construction would do little to protect your feet (or even the rest of your car) from damage caused by scrapnel pieces that used to be your clutch!!

As far as I know all SFI rated bellhousings (scattershields) are made of steel. That is what you want if you are going to drive a high performance hard!

PS: if you go fast enough with an automatic and you will need a trans blanket to protect you from a transmission exposion.
