I am looking for the stove pipe and the tube that runs from it to the air breather snorkel. I don't have the stove pipe that sits on the exh mani nor the tube up to the breather. This set up puts the hot air to the carb on cold starts.

 

My car is a 350 motor. This set up the same on any other GM car of the day?

 

By that time the connector pipe itself was aluminum flex hose which is pretty easy to find at a parts store. The manifold heat stove itself should be same 74-76 and possibly 71-73 B&C body cars. IIRC it's a two piece affair which may require pulling the exhaust manifold to install- which opens up a whole nother can of worms.

Never understood why people will pull stuff like that off a car. They get the idea that anything to do with smog control is bad and junk, when in truth the ThermAC was a great idea and doesn't cost any horsepower to operate.

Now I'll admit to not being above sticking a BB in the end of the EGR vacuum hose, because EGR has made more engines run poorly than anything else I know of.
