Is the AIR system worth keeping on a engine. Before I decide to get my engine rebuit to stock or slightly mild street usage I would like opinions on tuning issues or reliability. Any issues with vacuum troubles. Does anyone manufacture replacemant hoses for this system. I have the complete system still on the car.
Thanks

I had it on my first '67 and yanked it off on day one. However I did keep everything. The pump was all seized up and I didn't see the point in rebuilding it. I guess it's kind of neat to see an operating system at a car show (at least outside of California), but that's about all it's worth in my book.

From what I remember it just used standard heater hoses, but they might have been replaced a few times before I got the car.

i think you should keep it just for oringally .plus if you every decide to sell the car you can add it to the valuve

If you decide to yank it, and don't want to keep it, I will take it off your hands.

I kept the A.I.R. system on my 67 H.O.but made it non functional. Take the guts out of the housing ie: vanes, carbon shoes etc. You don't see to many at car shows and it doesn't effect performance. Does make it a little crowded though.

I still have mine, what are they worth?

If you're going to make it functional you'll probably need to use the correct molded hoses-not just pieces of heater hose-since the required bends would kink and choke the air flow off. I removed the vanes from my pump since they were shot and at the time you couldn't get replacements...maybe they're available now? You'll also have to plug the threaded holes in the front of both heads if you're going to disable/remove. I had removed the set-up altogether years back but now I kind of like it..here's a few photos of the bits and pieces. Jim.

Thanks for the info, I have the molded hoses and all the parts. I may just remove it and put it on a shelf in the basement. Does anything have to done to the stock distributer and Rochester carb with the system removed.
Thanks

Hi Tom,

I happen to be detailing the engine compartment of a CA car 67 GTO for a customer. This car has the complete smog set up on it. I think the hose clamps have been changed but other than that looks original. The car runs fine and the smog set up dosesn't appear to have that much effect on the tuning. It only requires vacuum to operate and doesn't look like it would cause any problems unless the vacuum actuator would be faulty and leave an open port. The rest of the system works through the chamber that runs along the edge of the cylinder head just below the valve covers. This is my first time working on a smog car so I am certainly not an authority but this is just my observations. I do have a question about the fuel lines on your car. My customers car has some funky set up that comes up on the drivers side of the car and has a filter, rubber lines, and steel line contraption that leads to the carb. It looks partially stock. With the car having the air pump I assume the normal steel line has no room to feed up through the front of the engine. Could you let me know what kind of set up is on your car? Also if you want to sell your air pump set up I would be interested in buying it. But you should keep it if your car is all stock or could be put back to stock easily.
