Heck we still polish lines and exhaust systems and clean carbs for AACA national events. My area was a bunch of street racing in 61-66 as our local track didn’t open until late 63. There were no 61 409’s in our area but one of the best was a 61 350 with gears and bucrons and was the best for couple years The engine still exists but the original car is long gone.he only picture I have is a high school newspaper photo, won the High school car show used to clean carbs with tooth brush scrubbed undercarrige and polished fuel lines with semi Crome polish. Loved that car!
