Hello! I have an issue I believe I've narrowed down to my distributor. It's a '66 200. The distributor is a Delco-Remy HEI. The car starts great, idles and revs nicely when the car is in park or neutral. It idles fine when in drive, but when I give it some gas it shakes and sputters pretty badly. I swapped in the original distributor with a Pertronix electronic setup and it runs great, even when driving. Put the HEI back in and had the same problem again. The carb is a Daytona CHV Universal carb, but it did the same thing with the 1100. I can't find any vacuum leaks. Vacuum advance holds vacuum. I've replaced the Transmission Vacuum Modulator. Any ideas on what could cause this?
