Source please?? The dyno tests I quoted were from Chevy's own records, they did state that the heads were Traco Racing prepared heads, nothing was mentioned about the rest of the engine being any different than a production engine. Do you have any idea what made the SCCA racing engines different from the production engines? Besides the prepared heads?? We've been looking at a video for a few months of a dyno run of a basically stock DZ302 that had a run of 530HP @ 8,500 RPM. The old 302s would turn in excess of 7,000 RPM right off the production line, don't take my word for it, ask any of the 28,103 owners that bought one '67-'69.
