I finally finished my '50 Chevy project and have taken it about 300+ miles now. All is going ok with the car other than my ears will not stop ringing after I get out of it. There is a high pitched whine coming from the distributor. I have an HEI in it and its a 355 SBC. It doesn't seem to effect its ability to run like it should but it is getting annoying. First I pulled the cap and see no signs of anything rubbing. Then I swapped to another distributor.. the problem still continued. So I shimmed it up with the largest Teflon shim in the Moroso kit. Still whines constantly. The noise does go away when I get on the gas. So it is really a 1000 - 2500 RPM issue Any help or suggestions would be appreciated.
