I dont think Matt was implying they bend over time. He's talking about metal fatigue leading to ultimate failure of the part.

Yes for low cylce fatigue you get plastic deforation very quickly and failure but high cycle fatigue is harder to predict without some materials science, which requires analysis of the rod material and putting it into some very fancy software to analyse. Sounds easy but takes alot of effort. Even then the point to faliure will vary as it depends how people drive the car.

I look forward to hear what Edlebrock have to say when you tell them "350WHP blew a rod out the side of my block but it worked for the first 20k miles". I'm not a gambling man but I bet it will be along the lines of:

"we only guarentee 242WHP so sod off"
