Smog pump removal while keeping AC

Post by blue-pteyra » Sun Aug 12, 2018 10:53 pm

I have a 1966 390 AC car that has all the pieces of the smog/air injection pump intact and working.
I really do not like the way it looks and I hate working around it.
I want to remove the pump and related parts and replace the pump with an idler pulley to keep the AC belt on the car.
Is there a nonsmog idler pulley set up that is available?

Thank you

Hope others can answer your question. Something to check are inspection requirements. In Missouri, an 'antique' licensed car does not need an inspection. If you license the car as a standard road car, it needs a safety inspection. Emission inspections are for '96 and newer cars with OBDII connectors. However, factory installed emission equipment must be installed (not necessarily working) to pass during the safety inspection. A car this old I can't imagine any one is checking. Usually the inspector is worried if a catalytic converter is missing. Check with a mechanic before dumping the stuff, I had to talk pretty quick after removing my broken pump from a '87 F250 with a 460 and it never did need an emissions inspection.

Hope you find the work around.

In California, pre-1975 gas-powered cars are completely exempt from emissions inspections.

I thought that I would mention this in case you are not aware of it: The manifolds that return gases into the exhaust manifold from the pump have fittings that are threaded into the manifolds. These holes will need to be plugged if the smog setup is removed. Plugs were available from Ford many years ago when I removed the system from my ’66. I don’t know if they are still available, but if not maybe someone has a set??? Otherwise, maybe some properly threaded steel plugs might work.
