John;
If we knew what stress was on the aluminum rods, we could look on an "S-N"
diagram for that particular alloy and find out how many cycles to failure to
expect.
How long you can run aluminum rods depends on the engine's horsepower, RPM,
stroke, etc.etc.
You'll know when you've run out of fatigue life on those aluminum rods when
one breaks. If it were my engine, I'd at least inspect them with a dye
penetrant test such as Zyglo to find any cracks before things go
catastrophic.

Gotta disagree with that one. Aluminum rods may cycle sooner than steel
rods, but what's a short time? I've had my best success at Bonneville with
aluminum rods and still using them.

On the other end of the spectrum are aluminum rods-- they are guaranteed to
fail after a short time. That's OK for drag racing where they are replaced
after only a few runs.
