Thanks for the video, it put a big smile on my face. Intermittent speedometer is a common problem on 3x8s. Its usually the sending unit at the transmission. If u do a search you will find pleanty of information.
Nice job guys. Took mine out this morning before the rains come. Haven’t been out for 3 weeks now. Little shorter trip. Just down 70 to page, page to miami, down miami back to 70 and tucked in for the next 2 weeks. Great sounds and the video looks great. It’s amazing to hear how quiet the fuel injected 308s and 328’s are compared to my 78. Best regards and stay safe. JP. BTW I have an accurate speedometer, but a tech that reads 2X....you should hear the sound a 308 carb car makes at 12,000! ;-)
