One of Chevy's own dyno tests for their 302 Z/28 engine dated 8/2/67 showed a single four barrel version with 440 HP @ 7400 RPM and the two four barrel version with 468 HP @ 7400 RPM, the fuel injection version (which was never put into production) was 470 HP @ 7400 RPM. According to the data sheets accompanying these tests, they were using Traco Racing prepared heads rather than the stock heads, otherwise the engines appeared to be stock.
