I posted an ad on the clasified board but am getting no responses yet. I tryed a part number for a injecter at GMpartsdirect.com and had no luck either. I would like to get a pair of 85# rochester injectors new or used. If any one can help hook me up it would be great.

 

You're gonna have to look on ebay or in a junk yard.

 

The earlier 454 injectors are supposedly 85-90lbs/hr.
According to Mitchell and Alldata they are 17111784's and were used from 1987-1990.

 

accually the earlier ones were the 80 lbs and the later model ones are 90

here are some numbers

80 1708430
90 5235231

 

firedawg225, I tried those PN's at gmpartsdirect.com and came up empty. Brent, I tried 17111784 and came up with a price but they had no information as to application or flow rate. We could assume they were 85-90 lbs/hr but it would be nice to know for sure. Ive seen different charts and dont know which are correct.

 

If you want application try:

I bought mine from Orellys and adavnce auto. those numbers work for cross references. or you can do a search on the boards there are alot of threads with injector numbers. there are so many to name it's easier if you do some searching.

I bought both 65 and 90lb injectors. and used the numbers on my web page which is what i gave you.

 

Try 17112560 for the 80's. I took that from z28boy.cz28.com , there's a lot of good pn's there. He doesnt have the 90's though.

 

i have 90 lbs in my car gmparts direct. if you dont have a part # or year make model they are not of much help. if you like i can give you part#. email me. i will look up this evening. i am guessing 1990 chev truck 454. for some reason they upped size from 80-90. maybe 454 SS not sure. thay info on crossfire forum with search.

 

I bid on a pair of 75 PPH injectors in a pod on ebay but some one wanted them more then I did. I think I'll hold out for some 85 or 90 PPH ones. Finally found some at gmpartsdirect but they are kida pricy. Still looking arround for some used ones for sale. I posted another add on our classified board but so far no luck.

 

How much is pricey

 

You are lookin at 50 to 70 bucks a pop for new GM ones.

 

i think a lot more than that from gmdirect shifty. i have 2 new ones out of 454 TB that i will sell. TB is 1995 454. that is the issue. no one knows the #'s! the part# on it cannot be cross referenced. the FP is 26-28 per manual so that tells be 68 lbs BUT a 454 application. my 90 lbs are 12 lbs. so it would appear 68 lbs at 26 lbs is equivalent. the part # was posted several times. no one knows. i contacted a rebuilder and they have no GM#. brand new. anyone interested? i also have used 90,000 miles 65 lbs out of my vette,

 

$99.00 a piece at gmpartsdirect.
