OEM Rod Bolt Stretch
Hey guys, I've searched and searched for the answer but haven't found it yet and it may not even exist. I'm in the process of rebuilding my 5.4 and I plan on using new ford rod bolts, I have the torque specs but would prefer to use my stretch gauge instead. Does anyone have any stretch specs for the tty rod bolts?

I don't mind doing it per ford spec but it would make me sleep better tossing my gauge on just to double check everything, especially with something as critical as rod bolts. If I didnt already have the oem bolts I would go with ARP but I can't justify that with a new set of ford bolts sitting on the bench.

But again the question remains why try to out-think Ford's own engineers and designers? I'm running two 5.4's one with over 275K miles that work perfectly, the other just topping 217K miles also pretty much perfect.
If we're building NASCAR or NHRA engines then yes different procedures are called for----stock engines simply don't need more than what's already there from brand new.
I believe in some instances we can improve on OEM things but trying to incorporate exotic high performance parts into a stock engine seems a waste of time and money. In this case we might be worrying too much about nothing, loss of sleep can be avoided by accepting Ford did a great job on the Modular Motors.

An ounce of prevention is all I'm saying. I'm not saying fords engineers don't know what they are talking about but to say that ford, or any other manufacturer of fasteners for that matter never have failures With their products would be ridiculous. I'm not questioning fords recommendations, I'm questioning the integrity of the hardware and to spend an extra 30 minutes or so to double check seems logical in my mind.
