Car is running rich
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?

I would pull the vacuum line off the fpr and smell for fuel look for leaky injectors as well as the o2s. Check the oil for fuel do not want a grenade.

7.8??? at idle? WOT? is this a wideband? 11.X would choke out the engine.
you will need to answer many questions. 95 PCM tables. tuned, Injector Rate.
Vacuum Leaks??? FPR diaphragm rupture? I would imagine your injectors are not leaking??
OK your forced induction. you could be dialed in 11.9 ish @ WOT. if you have a decent sized blower.

for safety. I would confirm. the basics. then pull and inspect the Wideband. O2. running that RICH. is known to destroy the O2. clean off any residue? and hope the AFR. was not a almost impossible 7.8 @ idle.

Good suggestions
No exhaust leaks ahead of the 02s?

again. for confirmation & safety. once the open air reading is confirmed. can you get enough O2 wire lead. to read. let's say a Camry exhaust pipe. As you know this should read about 15.2
