I just bought this 1969 Chevelle with a 1972 396 (402) and i noticed that the vacum advance on the HEI distributor wasn't hook to a hose or plugged up, just open. On the front of my Edelbrock 1405 carb it has timed vacum and a manifold vacum. The timed is hooked to the TH350. I moved the transmission vacum hose to the manifold side and hooked up a new hose from the HEI distributor to the timed side of the carb. The car flooded out after a take off and died. I opened the hood and could hear gas being sucked into my carb in timed gulps. I have a Edelbrock Victor 2-R manifold so there is no hook up for the transmission. I just put it back how it was, started the car and left and it's still like that. I just don't like the way it's set up eventho it does work. Any ideas, help or explanations would be very much appreciated. Thanks
