Dodge did do some crappy R/T models.

True

The heads for the original R/T were bored and a different cam was installed.

True, in the 70's

This is where you get your ping and your engine runs like **** without the extra octane that is needed because of the added compression.

On any modern Durango motor, False
On a performance build-up or an original Dodge muscle car, True

Extra octane retards the timing allowing the detonation to occur at a later time thus stopping the PING. PING is the sound of combustion happening at the wrong time.

True and True. Higher Octane forces the fuel to burn slower/longer. Ethanol BW, since it is a crappy fuel, is often 100+ Octane in order to get it all to burn.

This occurs when the piston is still at the slightest upward compression stroke and detonation happens. As the piston is forced down, the connecting rod is still moving upward so all that pressure goes no ware but into the rod bearings. There is some small clearance between the rod bearings and the crank. The PING sound that you hear is the rod bearings smashing into the crank.

False. "Pinging" is predetonation which means the fuel is exploding before the piston in the cylinder is in the correct position. If it isn't in the correct position, the explosion occurs in a smaller cavity, creating the Ping sound and potential damage

You will notice this much more on a newer engine's than an older one's because the clearance is smaller and hasn't worn out from everyday wear. The older more warn out motors have more play in them because of wear and the piston will actually be in the right spot (or close to it) when detonation occurs, thus the SLOP in the motor will even things out. It depends on the drivers that owned the trucks and how they took care of them.

Oh my. False.

Now a true R/T motor cannot run on regular octane.

True, a real RT motor ran on leaded fuel.
Sorry if that ruffles any feathers!
