Part number on top of throttle body injector is #gm17084304rpd

I got these on a holley 502-6 TB. The person before installed these and said they were 75 lb injectors for a 454. I found one item talking about this number on a web site and it talked about it being around 80 lbs and that is it.

I would like to have the lb rating at different pressures (basically the specs).,

Anyone got these or a good GM part number site. This wasn't listed on Stan Weiss's page either. Thanks in advance.

If you got the injectors from a holley TBI, then they are holley injectors...not GM injectors.

From what I understand...while they look very similar, they are infact different.

I suggest you start at Holley's website. Then try calling their technical support.

On the right is a GM TBI injector, on the left is a Holley TBI injector (though it's possible both Holley and GM have used other injectors in some apllications). Apparently the Holley injectors are very similar to Chrysler TBI injectors.

Does anyone have any info on the GM injector pictured here? I went to the junkyard this weekend to get a TBI unit. I also accuired 6 injectors for it. I got the two it came with (late 80's camaro 305). I also got 2 from a 4.9L caddy, and 2 from a 350 in a Chevy full-size van.

They all look identical and have no numbers/letters that I can find. I'm guessing they are all the same since OEM's save cash that way. What I was wondering is does anyone know the flow rate at 15 psi, or their resistance? I know they're low impedence, but what ohm number? Thanks

motown menace,

I believe the injectors are identified by the color codes:
