* SS Emblem: The SS emblem is typically placed on the front fender just ahead of the front wheel opening. It's positioned relatively close to the front edge of the fender, but not so close that it interferes with the body line or appears cramped. It's generally centered vertically between the top and bottom of the fender.
* 454 Emblem: The "454" emblem (only on models with the 454 cubic inch engine) was placed below the SS emblem on the same fender. Again, it’s generally centered vertically and horizontally relative to the SS emblem and the fender's curvature. The distance between the two emblems is relatively small, keeping them visually grouped together.
While precise measurements aren't available, a good approach for restoration is to:
1. Find original, high-quality photos: Pictures of original 1970 Chevelles with 454 SS emblems are invaluable. Look for factory photos or photos of well-documented, unrestored cars.
2. Use a template: Many restoration suppliers offer reproduction emblems that come with templates to aid in precise placement.
3. Symmetry: Ensure the emblems are placed symmetrically on both front fenders.
Ultimately, careful observation and comparison to reference photos are key to achieving an authentic and visually correct placement. Minor variations from car to car are to be expected.
