how can i tell what injectors i have?
 

I bought a 94, the guy said it has aftermarket bigger injectors in it, and you can definately feel and see that it does ha. But he said he has no idea what the size is, or what company theyre from. Is there any way i can tell what size and such they are?

bump for a valid question maybe

the question is, is there any way i can tell exactly what injectors i have in my truck? Without the box, or any other info, just the injectors in the truck

not sure you can tell brand or by any stamping, but people have been able to use measuring devices of a specific size to figure out sizes of branded but unknown size sticks. If you pull one and take it to a machine shop I'd imagine they'd have the tools to know if the holes are .010, .012, .014, etc.
IIRC .010s are factory 215s, .012s are 370s/90s, and .014s are 435s/150s. bigger than that is pretty big.
