How can I tell what injectors I have
I've got a speed-density TPI on a ZZ4 crate motor. I bought the whole motor together and running, but don't know a lot about it. Here are a couple of photos.
There are no markings on them that I can see. I'm not afraid to pull the rails and take one out, but don't want to go through that effort just to find that there are no numbers or markings on the bottom half either.
Colors in the photo may be a little off - these are an olive green with yellow tops. Doe that color scheme look familiar to anyone with aftermarket injectors? Is there any way to tell if they are 50s or 30s?

I put a set like these in a mustang and as a guess I would say Accel maybe. 19 to 22 pds.
