On a '91 with a 350, TPI. I'm going to use short headers, and dual exhaust. What do I need to do for the oxygen sensor.

Thanks, Pat

I don't know. But, I'll extend myself and say that it doesn't really matter...assuming that it is mounted close to the original location.

IOW, close to the original location is all that matters.

Napa has O2 sensor bungs, and they are cheap, like 2 bucks. All they really are is a nut w/the correct thread pitch (which is sorta odd-ball and you won't find it at a hardware store).

A sparkplug non-fouler is the same thread. I have read of folks using them to defeat their cars computer...when you have a sensor upstream and downstream of the cat. It spaces the sensor out of the exhaust flow and gives it a faulty reading. So, you could use one in a pinch, but they aren't the best. You'll have to drill the end so that it is big enough for the sensor to fit in.

Sorry for the delay in getting back to you.
Thanks, I'll see if I can get a bung from Napa.
