Hi Ron, I see that you also own (or have owned) a 1964 Impala SS car with a 340 hp 409 (Owned since 63...that’s awesome). I will be asking this group some questions in a week or so, hoping to confirm if my car’s casting Numbers, date codes and engine stamp are all correct or if someone has tried really hard to make them look correct. I look forward to your feedback. ThanksVery nice 64!!!
