Perhaps I misremembered. Seems difficult to find some written sources on this.

In my quest I stumbled upon this[1] article where they discuss composite connecting rods for Fop Fuel dragsters:

Designed for Top Fuel engines, this connecting rod is half the weight of a conventional aluminum rod, yet is projected by company engineers to last an entire season instead of just 12 to 15 races.

Seems they're still at it, perhaps it'll be the next thing?
