Great to find this place. I was just searching the net for a question regarding my 73 sportroof..seems this was the only place i found my answer,,,and believe me i did look. There was a thread regarding the 2 vacume sensors on the front of the cleavland. They are linked to the carb and vacume advance to speed engine in overheating situations. My question is can i plug those off?..i rebuilt the motor and have the edelbrock intake and carb..really nowhere to route those sensors with all the old setup gone...i live in canada..so its not like the car will see a day over 75 degrees anyway.
