Re: 1970 vs 1971 Z28 (apples to oranges?)
The drop of two full points 11.0 to 9.0 adv in compression ratio is key. If you took a stock L78 and dropped the compression two points you would get an idea of what the difference would feel like, however it is more dramatic on the smaller 350 engine.
The low spoiler was still available in 1971 as an option.
