210° @ Cruise and 180° @ Stop? What's Going On?

Too much vacuum advance? If you are running it try it without. Either way it could be too much timing. There also could be an air flow issue in the grille or core support. The rubber seal on the front of the hood may be missing. Does your shroud have the vent flaps for speed?

No seal on the bottom of the hood. I have an AAR/Stinger fiberglass hood that uses low tension springs and rubber bumpers. Latched with Eddie Motorsports hood pins.

Do you have a picture of what the seal or flaps should look like? Never thought this would be the issue.
