people say these engines are built to rev, but perhaps a life spent at redline is a contributor - bits moving faster, more heat, etc. modifications tend to encourage harder driving?
Right on; more redline more stress; but higher M96 rpm apparently puts the ims bearing in a more stable symmetrically loaded condition and piston ring oil film strength is better. Perhaps this where the "made to rev came from". Maybe it should be have to rev?
