Hooker Side-Pipe Headers and O2 Sensor?

I have a set of Hooker stainless headers going on my 68 and I eventually want to go with FI. I want to get the O2 sensor bung welded on before I mount the headers. Where's the best place on the headers to weld the bung? Right side, left side? How far from the heads themselves? is there an optimal distance that will provide the right amount of heat so I don't have to use a heated sensor?

Thanks!!

Is there just the one sensor? My setup needs an O2 sensor & I fitted it in the reducer on the drivers side. It works fine, but I have heard of people needing to fit a heated sensor in the same place due to it cooling off at idle. I guess the ideal spot would be in the collector, any closer to the head & you'll just be measuring the O" levels from one cylinder (as opposed to 4 of the 8). I suspect that I don't have any cooling issues with the sensor as I'm running ceramic coated headers. The advertising claims that the ceramic coating retins heat and, going by the reduction in cabin temps after fitting them, I think the claims are true. I could find that plain steel headers would cause me sensor cooling problems? Stainless isn't as good as conducting heat as steel, so you may find that you'll be OK with a stainless system (I've got stainless dual pipes & the heat coming off of them under the rear composite spring is a lot less than the stock steel system used to give). Wherever you fit it, ensure that the sensor tip is high up in the pipe so that it doesn't get contaminated from condensation.

02 sensors?

I have Hooker side pipe headers and use two wide band sensors, one each side on the top of the collectors. No FI, just used for testing fuel ratio.

I have 2 heated ones one on each side in mine down low facing the frame so you cant see them.

By heated O2, do you mean wideband?

You do not have to worry much about where you mount the wideband O2 (within reason of course). I would highly recommend going with the wideband over the traditional O2 sensor; better tunability and somewhat better low speed drivability.

A heated O2 sensor is a standard narrowband part, but it has a heating element inside. Some OEM applications use them.

jethot direct and hooker headers

I ordered my header/sidepipes through jethot's direct purchase program. They worked with Hooker to have the bungs welded in place before being shipped to jethot for coating. The bungs are located in the reducer area facing toward the frame pointed slightly downward in a 5 o'clock or 7 o'clock position depending on the side of the car. I installed a wide band O2 sensor in the driver side to work with an innovate a/f monitoring system. I plugged the other side that was not in use. It is amazing what you can get done when you are willing to pay $1200 for a set of coated headers. I was very pleased with the way the headers were packaged and the quality of the coating.

Thanks!!

Guys, thanks for the information! I guess I was thinking since the collectors are outside the frame rails that although its the typical place for the O2 sensor that is was not the right place for the side pipe headers. I haven't installed the headers yet so I wasn't sure where everything lines up.

So you guys are saying that I can mount the o2 sensor at the collectors and assuming I'm using a wide-band, the distance away from the engine is not an issue.

I guess I need to mount one side and then mark a spot and get it welded there.

Thanks for the assistance!!
