It has been done by many people, who still drive their cars after many miles and years.
What are the true limits for reasonable longevity / reliability (for your average person who drives his car daily and "steps on it" now and again) of the LT1 when adding an LT4 PD blower setup (ZL1, CTS-V style?) feeding 93 Pump gas through a LT4 fuel system?
Given that the tune has been done correctly, I.E. by an experienced tuner who knows and adheres to the limits of such setup...

If you’re worried about longevity on the stock LT1 shortblock, you can keep boost reasonable, say 7-9 psi. Upgrade the fuel system to run at least some E (E30-E50 is a big help) to help pull heat from the chamber like King described. If you only have 93 to work with you’ll want to keep boost about 7 psi with the 11.5:1 compression. The stock LT1 shortblock simply will not tolerate very high boost on 93 octane only for long.
