I have a friend whom is doing a rebuild of an old Torqueflite A488/466 for a 1960 Plymouth Fury. He's wondering if it is possible for him to forge the casing for the A488 from Aluminum instead of Cast iron. It would be identical in design to the older casing but made of aluminum rather than cast iron. Is it possible, to make it work would he have to change the materials used in other parts as well?

The correct denomination is A466.
Interesting idea, it should be doable but on the expensive side for just one casing?

Shedding weight is THE best way to get improved performance, however in case of the A466, that weights a ton, it happens to be in the close to perfect location for the center of gravity in a car.
At least it moves some weight to the rear. Moving weight from the front to the rear makes a giant improvement in handling. If you relocate the battery to the right rear of the trunk, for instance, makes your car handle and go around turns like a completely different car.
So I do not think that an aluminum A466 is worth the effort.
I recall a road test of a post 61 Mopar in an old magazine that said the older cars handled better. Certainly suspension geometry wasn't the reason for this.
Fact is, the 57-61s with CI Flites had almost a weight distribution of 50/50. Running a BB that can be easily upgraded with aluminum parts (along other mods,
battery in trunk, etc) you can easily bring it to 50/50. I'd like to see aluminum BB-heads with heat crossover!
