The #s on the side of the body should tell you there original application if they had one, but if someone has modified a set of cores the only way to tell what they are is by using a pin gauge and/or boroscope

I'll look for some #s.

I bought the truck off a dealer lot and they gave me the PO's phone #.

The PO was REAL tip lipped about any mods he did to the truck. I believe he knew there was a problem brewing with it because the truck blew a head gasket (2) days after I bought it.

I can't imagine my truck having OEM injectors with all the other mods the PO did to it.

Also, I believe the dealership "De-Tuned" the AFC after they repaired the headgasket. I turned the Star screw out the other day and it came ALIVE.... BIG TIME !!!
