Actually there is not truly an arbitrary safe number. The big issue with the stock LT1 engine is that some have crazy tight ring gaps from the factory, making them more susceptible to heat-related problems. So you can get away with more on some engines than others, problem is that you don't know what you got unless you take it apart. Cooling things down with methanol and E85 helps with heat, but still no arbitrary number that is guaranteed to work in every example of the LT1, or every situation. Drag race is one thing, 20 minute HPDE sessions will build more heat and therefore more of a concern.
For your M6 car I would actually suggest nitrous oxide as your power adder for drag racing instead of a supercharger. Stuff works awesome with a stick. I have seen an M6 SS on drag radials that ran 11.5@119 off the bottle, then spraying what he said was a 150 shot, he went 10.8@128. I have seen some M6 Camaros with blowers here and they were not as quick as that nitrous car, and yes with MTs on all of them. Plus if you want to do HPDE (assuming that's what you meant for track it), just remove the bottle and it will not be a problem. Adding a supercharger of course would make it run hotter during HPDE driving. FYI I had a supercharger on my SS before, so not against superchargers in the right situation, just pointing out some things that I've noticed over the years.
