Many 4.6 fords were in the shop for a broken no.7 int spring-beehive 5.7 hemis have had there share.
Maybe ford bought the springs from comp..lmao..

That's not proof of OEM beehives breaking at a greater rate than "normal" (whatever they are) springs.

If I went and researched to list 10 more examples/ motors in production 'past or present' would it change your view some?

No, but actual evidence would.

How many OEM's have stopped using beehives/conicals due to excessive failure rates?

If the answer is "none" then what does that tell us? Indeed, why did OEMs go to beehive/conical springs in the first place if they are such a poor design?
