However, you can find various diagrams and information from several sources:
* Repair Manuals: A factory service manual for the specific vehicle the 454 was in (like a Chevy Silverado or Suburban) will have the most detailed diagrams, including wiring diagrams, component layouts, and exploded views. These are often available online (eBay, Amazon) or from auto parts stores. Searching for "1997 [Vehicle Model] service manual" will yield results.
* Online Parts Catalogs: Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts often have online parts diagrams. You'll need to select the year, make, model, and engine to find the correct diagrams. These are usually less detailed than a factory manual but helpful for identifying specific parts.
* Chilton's or Haynes Manuals: These are less expensive repair manuals than factory manuals, but offer decent diagrams and repair information.
* Google Images: Searching for "1997 Chevy 454 engine diagram" or "1997 7.4L Chevy engine diagram" might yield some useful images, though their quality and accuracy can vary. Be cautious about relying solely on these images.
Remember to specify the *exact* vehicle model (e.g., 1997 Chevrolet Silverado 1500) when searching for diagrams, as this will ensure you get the correct information for your specific engine variant.
