Air-fuel gage is reading 7.8
Seeking advice on places to start looking Vortech S-trim on a 1995 383 LT1 with AFR heads & a custom cam Had the discharge pipe from the blower to the throttle body pop off a couple of times the flood of fuel lite off in the exhaust, flame out the exhaust wondering if that fried the O2 sensors thoughts? |

flame out exhaust... that is always bad for an O2 sensor... Same for cats if they are still present.
Even if the flame isn't burning at the O2, the fuel is there, soaking the sensor. I would start there. |

I agree.

O2 readings from Lt side vs Rt side???
Static FP tests with leakdown time? Leaky INJ (excess fuel, NOT burning), will light up in HOT exhaust pipes, from 'lean' burn... |
