I didn't leave anything out the OP has a 1LE which has a suspension drive train similar to a ZL1. TR6060 has handled 1000whp+ in many builds over the years. But that is a Moot point with your 220 tire wear stipulation. You won't break anything with 220 wear tires anyhow....even if it was a SS.

As already noted I was replying to the old sad saw of bolting on a PD blower fixes all problems on a LT1.

Now to your comment since we are now talking about a bolton PD blower and slicks going 10s. Hmm, I don't see blower and slicks on a LT1 doing 10s. There seems to be a lot more mods than that from fuel to custom tune. Remember here you already said this is a KNOWN M6 setup. I'd be intrested in a PDB only (I'll even toss in custom tune as we are having a conversation, and we both know can tunes suck), slicks doing 10s with a M6, that would be great, to my mind this is not the norm, but I don't pretend to know all the is about PDB.

Now let me address the TR6060 in specific and the LT1 based engine and drivetrain in general.
1) Tremec says 550 ft lbs is the limit of the 1le or SS M6, 650 ft lbs for the Zl1. Clearly at some point and over a period of overload 1st gear will fail. So despite anecdotal evidence via the internet about 1000 WHP on stock 1LE TR6060 is not backed up be the actual mfg of the trans. From my experience the higher the overload, repeated offten, leads to a quick failure of component. That does not negate that a stock LT1 based TR6060 can't deliver 1000 WHP... it just asked the more important question of how long?

2) The LT1 engine is significantly more fragile under boost vs the LT4, GM did a whole bunch to the LT4, all the crank, valve, piston failures in the LT1 had to be known by GM as these are the areas that are upgraded... go figure. GM does not put titanium valves in an engine if the plain valves "work". Same goes to the rolled fillet crank.... down the list.

I would since we are having a conversation, like to see how many M6 LT1s with PDB as the only mod into the 10s (slicks prep track). That would be cool. I like it when the Camaro is faster than I think is possible and / or the norm, at least none show up on a cursory inspection of the quick list.
