What he's showing you in this next pic is,
Two bolts found in the oil pan, NOT EVEN ATTACHED TO THE MOTOR ANY MORE : o () "YIKES"
As you can see, he's showing us that the treads are perfect,
(and were clearly soaking in oil) indicating they were out FOR PROB SOME TIME.
I bet one of them belonged there

How come no pics of the main bearings? Don't you think that if the mains moved enough to cause the rods to go, that the main bearings would be pounded to death???
These pics show a scam pulled on Ford and the fact that the Ford service rep fell for it shows just how pathetically stupid they can be.

I'd also guess MAYBE 1% (if that) blew up racing. Prob 90% will tell you they were crusing at highway speed, no warning, AND BOOM

My guess is
AND I MAKE THIS GUESS BASED ON THESE FACT's:
thousands of Lightning's left the factory with Lose Spark Plugs, Front Ends that were shifting all over the place
Lose Ground Effects (front, side, rear, spoilers,etc)
Windshield Gaskets that feel off within a few weeks or months
BIG *** Bolts that fell off the Chassis (still dont know where they go)
Lose Rear Window Gaskets
ETC
ANOTHER WORDS IT'S EXTREMELY OBVIOUS, FORD HAS A MAJOR ISSUE OF "NOT TIGHTENING STUFF" and one can only assume
NOTHING is double checked. If it is, it must be Stevie Wonder doing the checking, hehehehehehe...................
oh btw, mine had every entire thing I listed above, just like THOUSANDS of YOU, my guess is THOUSANDS of US are driving arround with lose or missing Rod/Main Bolts RIGHT NOW.
EDIT
Don't get me wrong I agree with the Detonation causing it,
Any sound L motor that Blew, Prob had Detonation 100% of the time. I just happen to believe, either you have a good motor, OR YOU DONT. And Mods, or what your doing at the moment DO NOT play a part for THOSE FAILURES, and I do believe those failures are out there, and are caused by lack of quality control on Fords part.

What all is involved in having someone go in and check the rod bolts? Can it be done with the engine in the frame?

It's sad for the person it happens to but I'd suggest there are more modded L's that haven't thrown a rod than those that have by a factor of 100:1. If there are any un-modded blown motors out there I'd look for a similar cause, inexperienced operator.

I am not too sure about that.
With the crank shaft constantly spinning I am sure that the lobes would also cause severe damage to those bolts after driving hundreds of miles. consider that at cruising speeds the engine is spinning at 2200-2500 rpms, those bolts should not look so good.
If I am wrong in my assumption let me know what you guys think.

a loose rod cap bolt, like the picture would result in a prematurely worn bearing that would start to knock and ruin the crankshaft ......

It would be pretty much impossible for the engine to run with loose or missing rod bolts. The first time the engine is started, the bearing would spin and the rod would probably eject through the side of the block. More than likely it would wipe out the crank too. IF an engine came from Ford with loose rod bolts, it would self destruct before ever leaving the dealer lot.

a big
to the remaining bolt and cap....,the cap is in place in the picture....so it appears to be possible.
I know that the bolts, if properly preloaded, see only a fluctuation in tensile stress. The rod beam sees a full reversal, from full compression to full tension, repeatedly.
(actually, under load, will only see tension every two revolutions, on the inlet. It sees reversals at the transition from exhaust to intake, then from intake to compression, right?)
Rod bolts also experience bending loads, primarily due to deflection of the rod big end under tensile stress at TDC. I understand that this is one reason why bearing inserts are tapered in thickness toward the rod cap parting line, preventing metal-to-metal contact. How large of an effect this is relative to linear clamp loads I don't know. I'm sure others can answer this to validate the pictures.
