There's a lot of other stuff that won't be usable in a 70 year old car by then too!Ford had problems with them early on, but there's "fixes" for them.
Most brands have issues with early, "prototypes" that they sell us guinea pigs.
Due to the nature of plastic though, I don't anticipate the manifolds to be usable on a 70+ year old car.![]()
But, there's old stuff out there that failed at high rates too. Try find an original flathead Ford V8. Lots of them are cracked. We just forget about the stuff that fails, and 60 years later it's faded from memory.
I think a lot of the reason that older hardware is still available was the power per cubic inch was low. When you start pushing power density up, reliability and lifetime suffers. Some of those old flatheads would make 1/10th of a HP per cubic inch. They just weren't pushed hard enough to hurt themselves.
In my experience Honda does that with their small engines. They last forever because they keep them detuned.
Every design is a compromise. Cost, power, expected lifetime. When we want a lot of power and low cost we get plastic in our cars. Don't forget we're telling these guys what we want by what we buy. (Except when the government sets limits and rules, etc.)
