Need Opinions. Have nothing to compare to.

Thanks Mattax. That's good information. I now see why you questioned the A/F curves on my Dyno graph looking so different and inconsistent. It would lead me to believe he wasn't applying the throttle consistently. The missing portions of data in the middle of runs doesn't help much either considering we lost most of the dark blue run and chunks of the green run.

I just bought a bunch of parts from someone who just left where I work. He will be moving and is trying to downsize some of his parts inventory. Picked up a complete set of 915 heads, HP Exhaust manifolds, a spare Demon Speed Demon carb, and this weekend I am picking up the complete 400 (906 heads and Edelbrock dual plane intake) that wouldn't quite fit in my back seat :). I can use a lot of those parts for my Charger rebuild.

Reason I am mentioning is he also has a WBO2 sensor, complete with all the wiring, connectors, and led display (red & green lights) that he said he'd sell me for $25. He was running it in his '72 pro-charged 440 Charger, but says he is building a new 383 that will have ported fuel injection and says he will have no need for it.

I'm thinking I will buy it from him and wire it up. I don't know how accurate they are, but I figure at least I will be able to see if I am having any major A/F ratio issues. I don't know how else to check it on an older car like ours. I tried to look up A/F sensors, but they all seemed to be designed to plug into the OBDII port (I think that's what that connection under the dash is called).

Thanks again man! I really do appreciate your patience and the learning opportunity you provided!
