Ok, our GM computer system at the dealarship is pretty retarded, so here are the numbers I got in the time I was there, along with the partial table left on a post a while back From UnderDogRS. pn# 17112400 88-92(L03)5.0 liter pn# 17112493 91-91(L05)5.7 liter pn# 17112560 1990 (???)7.4 liter ( pn# 17100372 pn# 17100373 ) Are 68lb hour flow matched injectors that I have, from turbo city. They are Yellow/Brown also. Ill look into this tomorow. Here we go...<TABLE border=1> <TR> <TD>Color code</TD> <TD>Application</TD> <TD>Flow rate</TD> <TD>Part #</TD></TR> <TR> <TD>Green/White</TD> <TD>305</TD> <TD>40 lb/hr</TD> <TD>17112400</TD></TR> <TR> <TD>Orange/Black</TD> <TD>350 pickup</TD> <TD>55 lb/hr </TD> <TD>17112493</TD></TR> <TR> <TD>Yellow/Brown</TD> <TD>350 Cop Car</TD> <TD>65 lb/hr</TD> <TD>17112560 , 17112412, 17084327</TD></TR> <TR> <TD>Blue/Black</TD> <TD>Late big block pickup</TD> <TD>80 lb/hr</TD> <TD>???</TD></TR> <TR> <TD>Purple?</TD> <TD>Early big block pickup</TD> <TD>90 lb/hr</TD> <TD>???</TD></TR> </TABLE> Updated with Brents info and Pablos. 9-1-00 I'll get the others tomorow!!! ___________________________________________ 9-1-00 update. Instead of reposting this, ill just keep updating it here at the bottom. I couldnt get anyother pn#'s today, because i cant find what application had the huge injectors. What trucks. So im going to go find somebody with an AC delco book tomorow. Pablo-- I think the astricted number is a delco number maybe. I talked to a motorsports shop today and he said if i get a hold of a delco book, all the numbers will be different. Well see. Until then ill research what trucks had those huge injectors. and find out what other pn's these damn things go by. __________________________________________ ------------------ Gestapo?

Here are two more for ya! Ill see if I can get this posted at the top of the board. What do you guys think of having a little TBI technical resource up there with stuff like this?

<TABLE border=1>

</TABLE>

btw the green white injector has that little asterisk there at the end of the number thats not because i dont know it thats whats on the injector

BTW snuf, thanks! good work

Yes, a technical resource page with info like that would be great.

So should I include my 68#/hr pn#'s in the 65 catagory or did Delco make a 68#/hr injector. Are they just high flowing 65's that Turbo City matched up?

And, I should have the higher flowing injector numbers by 6pm today.

With the way that the computer works, It would help me out a lot if everybody would tell me exactly what model, year . Cars with tbi were made. Like what year trucks had 454 tbi. etc... What year where the cop cars made with tbi. Others cars/motors with tbi and their flow ratings. Anyhelp here would help me help you.

OH!!!

YOU GUYS ROCK!

snuf, if anyone asks, I'll be sure to tell them that you are the mo-fo'ing man!
Iam in awe!

17112412 is the part number I looked up for the 65lbs/hr injectors.

87-89 7.4L - 17111784 <cr>
90 7.4L - 17112249 <cr>
91-? 7.4L - 17112560 <cr>

BTW www.carparts.com is a great place to check ACDELCO part numbers and GMpartsdirect.com for pricing.

YOU GUYS ARE GONA LOVE ME.

I just ordered the emissions and fuel injection catalog from napa(catalog #21A-99). Its free for my shop because we do so much business with them.
AND,
Since my parents also own a GM dealership, after I get the catalog, I'll look up all the numbers from all the injectors(there are about 20 numbers for our type of injectors) and look them up in the computer, giving me the application. Then all I'll have to do is find out the flowratings. The catalog also has gaskets iac's etc...
Then I'll write up the chart and include as much other information as I can possibly find about injectors.

awesome snf! keep us posted

Snf, what a resource this is. I am interested in the Turbo city 68# injectors too. i wonder if they are just pumped up 65's.

I'll call turbo city tomorow.
I'll also share this site with you.
http://www.rceng.com/index.htm

Its the best fuel injection company I've found yet. The owner seems to be a legend in racing already.

Also the cheapest, fastest injector flowmatching and rebuilding I have found also.
