well, My 73 runs better than it ever has, and all I had to do was put the thermoquad in the trunk. hah with a holiday drive coming up, and a seriously leaking TQ I threw in the towel and opted for a new edelbrock 1406. bolted it on in the parking lot of Pep Boys in about 15 minutes, and drove off in a totally different driving car. It feels like the car lost about 2k lbs, very light and quick to the throttle. wow to be fair, the TQ I've been working with was a rebuilt unit that spent the first 10 yrs of life cooking in an arizona garage, but this car has never started and run this well, even when new. it is a joy to make something that ran mid to poor, perform so well. just thought I'd share. thanks for all of your guidence and invaluble info in the archives. Jack 73 much happier 81 alway happy
