I just got these; they are supposed to be 580cc. I just want to make sure before I throw them in. only marking on them is; 10350/4615
Thanks

 

check the number on top of the injector near the plug. It should have a series of numbers. Give us the number or google search it with word injector.

 

those numbers you are giving are not checking out.

 

my bad. 5135 17113841

 

Bump because I want to know too. I have injectors that look EXACTLY like that, but I have different part numbers around the rim:

Three of them say 1065 17113744, one of them says 1173 17113742!

Also, I was told these would fit the stock fuel rail. Will they?

I'm kinda pissed because I got these injectors from a well respected sponsor. I just found out tonight from this thread (thank you), so we will see how they react to my PM I just sent.

 

There are a lot of different size injectors that look identical to that, can't go by what they look like. Depending on where they came from, sometimes they're engraved on the body.

 

here is what the injector side looks like, any one at lest know what brand?

 

Well, I found out that three are 1008cc and the other is 785cc!!!!!!

They are Rochester injectors You're injectors aren't coming up... double check your part number maybe?

 

yup those are rochester injectors. The shop where i work is a dealer for those injectors. the numbers on the top of the injectors will let u know what kind they are. but u already found out too bad it sucks u got 3 1000cc and 1 785cc

Rochester injectors are the same injectors Precision sells...... except precision puts a pretty sticker on it

 

for some reason i cannot find a rochester 580cc injector although precision has one???

 

Did you double check your part number?

 

Also, are these injectors going to fit my stock fuel rail?

 

i search gm part # and came up with this, does it sound right?

Dynamic Flow Rate @ 43.5 PSI = 1.34 gm/pulse

(Peak-hold ECM driver modifications required)

Approximate cone angle for 90% of spray volume


Additional Information:
- Silicon grease supplied to lubricate o-rings prior to installation
- Ball & seat design with 6-hole diffuser disc. Same as MSD and Holley product.

 

Those injectors look just like precision's injectors :-)

 

they look just like my Precision 1000cc's

 

the housing/color look like precisions to me as well, not sure what size

 

i guess delphi makes these's and that look just like the rochester
edit: while doing a search they seem to be the same company??

 

when I ordered injector clips directly from Precision, they told me the clips come from Delphi so its probably all the same **** lol

 

Precision injectors = Rochester Injectors minus the fancy precision sticker and the increased price


on some of the rochester injectors, u might need to shave the top plastic peice right under the O-Ring. its sometimes thicker than what can fit in the fuel rail. u need to make them "import style" instead of "domestic style". i dremel tool can take care of that easily

 

yeah my precision 880's look like those
