Not Ranked
MRMAX,
I know where you were headed but the aluminum block for the 03 Cobra was thrown out right away after only a few prototypes were built. I will correct myself and say that the rods were the main cause of the failures I saw but the block added to the problem and is why both were changed out.
As far as F1 engines go, they have a lot of stress because they are running at 18,000 rpms and idle where some engines redline. Also the engines are a key component of the chassis and are considered a stress member. And now a F1 engine has to last 3 race weekends of practice, qualifying and race. So to say they are not stressed in an understatement.
Regards,
