Doesn't matter it's still a 427, even if there is no such thing as big block or small block designations still too many Cubic Inches there in my book plus its a complete different block than the LS3. Not the idea behind the original Z/28.
The change to the 350 was also when the Z/28 started a downhill slide performance wise.
