What injectors are these ?

Not that it matters. Just curious.
I bought this 85 Iroc with 71,000 miles on it.
was sitting for 10 years.
I’m restoring it from the interior to the body to the engine. I have the fuel system out. Tank out.
intake off.
New tank and injectors from South Bay.
Rebuilt the TPI fuel rail today.
Anyone know what injectors these old ones are that were in the car ?
Numbers on one side are 5-235-047
The other side 0-280-150-222


Thanks.

If they ohm out okay might be worth keeping. But in order to use them they will need to be cleaned and flowed. Assuming none are stuck shut with varnish.

I bought a set of new Delphi injectors.
I will keep them as spares for now.
They definitely have a different spray tip than the Delphi’s

I kept mine. But I also at least did the "home cleaning" with a battery, jumper wires and can f cleaner.


Yu might want to do that to clean out any gunk in there so it doesn't harden / get worse over time.
