[Shotimes] what is a "smog pump"?

[Ron Childs]

My '69 Camaro came with a smog pump. In case you need more smog, just turn it on 
:-)

Actually, it was an engine driven accessory that looked like an alternator or PS
pump that pumped air directly into the exhaust manifold. It had a runner down each
bank of cylinders and a branch that connected to each of the cylinders at the
exhaust manifold. Disconnecting it was the first mod I did to the Camaro.
