I have a ‘64 Signet 200 with a 225 /6. There is a noise that is made when I am in drive or reverse with my foot on the brake. When I give it any gas the sound goes away. Here is a video of my car in drive with the emergency brake on so I could record. It sounds like it is coming from my distributor. My cap was completely worn out so I replaced that, but the problem was not solved. Any ideas would be really helpful!
