Are These Injectors Stock or Aftermarket?

[imelmo]

Trying to figure out if these injectors I found at my shop are stock or aftermarket. They would either be stock ones out of my 2003 dually or the 225/100's out of ZMBYKLR before I got the 285/150's. I'm leaning toward stock since the holes look so small.


Also, if they're stock what would be a good price to sell them for? If they are stock, they were brand new from Ford but installed at a podunk place in Texas when I got stranded there for the NHRDA Nationals. They didn't torque them down properly. Only have a couple months of driving on them.

If they're the 225/100's I'll probably send them out to be gone thru and then sell them.

Only way to know for sure is to take them apart

You could get a pin gage set and get a descent guess at size of holes in the nozzles.

If you clean off the tip, is there a 100 marked on it?

Nah, no markings on the tips. I'm about 95% sure these are stockers. I'm gonna go ahead and sell them as stock cores.
