Not that high. A reason for that is because today's accessories are not nearly as damaging to power as they used to be; just like catalytic converters.
Maybe 375-385 or so, off of the top of my head, since 345 was pretty "light" of a rating as it is.

Above. LS1 was rated different in the Fbody and Vette due to stuff like air cleaner/intake and exhaust manifolds/system and GM wanting to protect the 'Vette as top dog in the lineup. Engine was pretty much the same.
