To decode a 1964 Valiant engine number, you'll need the complete engine number, not just "V1.73132".
Here's what you should do:
1. Find the complete engine number: It's usually located on the engine block, near the front of the engine. It might be stamped into the metal.
2. Look for a decoding guide: Once you have the complete engine number, search online for "1964 Valiant engine number decoding" or "Chrysler engine number decoder". You'll find resources that can help you break down the information.
3. Consult a mechanic: If you're having trouble decoding the number, a mechanic who specializes in classic cars will likely be able to help.
Keep in mind, even with a decoding guide, you might not be able to find every detail about the engine based on the number alone. It's always best to have the complete number for the most accurate information.
