If you have a 305 TPI and if you still have stock fuel injectors....what color are they, and if you know the numbers on them, that would help too, thanks!!

 

mine are black no clue about the numbers but ill check and get back to you later

 

Here is the GM a/c delco Part Number for the 305 19# FI 17111960 and the color is black. Again GM did not color code the FI's. Note! for 87-88

 

mine are green, I don't know what size they are, also do i have to take them off to get the number? where is the number located?
thanks

 

gm changed there injectors for the SD cars...

early ones are black and the later "multec" injectors were like a aqua color...

 

What is a "SD" car ??
mine are aqua colred, what size is that?

 

SD means Speed Density. it changed in 1990 i believe from MAF (Mass Air Flow) to SD.

 

you have 22#'ers
the 305's had 19#er's

 

yes, I know that 305's have 19lb and 350's have 22 lbs, but my car was originally a 305 that was swapped with a 350 block, but still has the original TPI, So I am not sure if the injectors were changed or not? I am trying to get the part numbers ASAP.
