Did it run well before the mods? Did you have change anything related to the injectors or wiring?

None of that should cause the engine to flood so something got messed up, could be a wire pinched somewhere causing the injectors to be held open all the time. Check fuel pressure and report back.

I’ll have to check the fuel pressure I’ve replaced both tanks and fuel pumps was running good on all stock parts got the edelbrock performer kit upper and lower thinking to get skittle more out of the engine brand new factory replacement injectors all new sensors too 61mm throttle body and shorty headers the rest of the engine is all stock inspected all vacuum lines no leaks but I have really bad exhaust leaks at the collector’s going to try to get everything out the pipe soon

Never removed the distributor new cap and rotor plugs and wires no fire visually jumping off any wires to ground but the plugs are excel header plugs might not be a great choice

Are the injectors the factory 19 lb/hr rating or something else? Are they the OEM pintle style one of the newer styles? If they are the correct spec they should work regardless of type but some of the newer types are prone to sticking open which will be indicated by fuel pressure dropping to zero quickly after shutdown.

the exhaust leak at collector's isnt helping, if you kept O2 sensor, its telling the PCM, lean, and PCM is adding more fuel, until you fix it.
I would clean my old injectors and put them back in, unless fuel pressure test shows new one's aren't leaking.

Do you really need those header plugs?

I'd put the spec Motorcraft coppers gapped right in & try that.

Welp put the old throttle body back on and some motorcraft platinums back in truck seems to run a lot better going to work on getting the truck to muffler shop to get some new collectors so all my exhaust is going by the o2 sensor plus I’m tired of inhaling the fumes 🤪
