GM has been in this business long enough that they have done their homework....and most certainly their bean counters have. They know there is a probability of manufacturing defects, what those defects most likely will be and what percentage. Example...........

GM puts out a crate motor. They know the likely and potential defects in material and manufacturing. They know the percentages. They determine a threshold of what power can safely be produced without these defects popping up and spec out the motors keeping all of this in mind. Said specs being within their comfort zone they offer a end user warranty for the motor AS IS when it leaves the manufacturing facility.

Scenario..........

Supersonic speedshop buys GM's crate motor and starts adding power increaser's that violate warranty and, as luck would have it, they do have one of the motors with the expected POTENTIAL defects and because of the end user added power, the defect rears it's ugly head and motor fails.

Now, if supersonic speedshop had installed the motor with no power adders and there was a failure, warranty should be honored and motor replaced following an inspection by GM to determine cause. But in this case we have the "SCENARIO".

Sonic tests and anything else that would prove a defect is irrelevant considering the warranty was violated. Not to mention the chances that something being found that GM wasn't already aware of is slim to none. GM put out a motor built to specs they were comfortable offering a warranty on and it was taken beyond this point by the shop.
