#'s Matching 340 build

I didn't get to the Carter carb yesterday. I did spend some time perfecting the dyno exhaust system and I installed a new dual wideband O2 sensor system. It works perfectly. What's even more interesting and impressive is I was able to compare the AFR readings from the dual wideband to the Superflow air turbine/fuel turbine calculated AFR readings. The average AFR from the widebands was 12.4 and the average AFR from the Superflow calc'd AFR was 12.3. I'd call that a win all the way around. Where the Superflow system lacks is at idle-you can't trust the AFR reading--with the dual widebands I was able to get the carb dialed to a steady 14..5-14.7 idle AFR on both banks. Exhaust temp readings with a IR gun we within 80 degrees on all tubes as well in the high 700's. I think Mopar knew what they were doing when they designed this intake manifold. I'm impressed. J.Rob
