John:
Don't forget about fatigue resistance. Aluminum has poor fatigue life
compared to steel. While the front engine plate is lightly stressed and would
be a good candidate for replacement, the rear plate is what melds the engine
into a single unit. The front of the engine and the rear of the tranny are
supported, but there is not support near the rear engine plate.
I would worry about flex between the two components, and resulting
cracks in the plate. I think to really answer that questions would require
some stress analysis. Intuitively, it seems questionable as to the longevity
of an identical rear plate fabricated from alloy. Just my $0.02.

Subject: [6pack] Aluminum Engine Plates
Hi All-
Looking for some thoughts on the aircraft grade aluminum engine plates? The
front one and the Transmission support plate. Are these strong enough?
