Exploding Torqueflites

FROM a guy who has done his fair-share of TFs in the past(albeit IN the distant past - I know nothing about the 518 etc) .....

ISN'T the problem the "fragile" front drum. Someone mentioned that this stock drum was cast iron. Unless they have changed this ...I thought that it was a "splintered iron". Which is a porous "cast iron" type material. Correct me if I am UNcorrect.

Now to the "problem" at hand. WOULDN'T just running a simple alum front drum totally eliminate any "exploding TF's" ? From what I remember - the alum drum is tested to well-over 16,000 rpms.
