Depends on which build of the 302 you look at. I think we can all agree that the 290hp rating was not accurate, if you look at the performance (ETs and trap speed) the 302 in production line tune was often on par with the 396/375hp performance. Dyno charts from that time period have shown some builds (not totally stock) with the Traco Engineering heads in Chevy's in house tests of their 302 development engines gave figures of 442hp @ 7,400rpm with a single 800 cfm Holley four barrel, 468hp @ 7,400 RPM with the cross ram dual 600cfm Holley four barrels, and 470hp @ 7,400 rpm with a Kinsler 8 tube fuel injection (a fuel injected version never went into production), these tests were dated 8/2/67. I think it would be safe to say that a production 302 was around 375hp.
