What this record proves

The badge is only the beginning.

Dual four-barrel induction takes the advertised figure to 425 horsepower in the same body and transmission. Induction is the entire difference between this record and the 410-horsepower one, which is why they are kept apart rather than averaged into a single 427 entry.

Both numbers are promotional claims published without a stated measurement standard. Treating them as measured outputs would give a false impression of precision, and torque again goes unrecorded and is published as unknown.

The two 427 records together show how a full-size manufacturer expressed performance in 1964: by cataloguing induction and rating steps rather than by creating a named package the way Pontiac did with the GTO.
