Re: Black and Green injectors?
What year did it come off of? There should be an 8 digit part number on top of the injectors. Get that and then do a search on here and you should be able to find it. I believe its 93-95 that had the 46# injectors at 28-32 psi which is what mine is. My injectors however didn't have any paint left on them. Had to look up the part number to figure it out. The 454 SS's were supposed to have 90# injectors and my excel file for calculating injector flow rate says the regular 87-92 454 truck injectors were 71#'s but I've also heard that there were some 85# ones as well. Your best bet is a part number search.

Could be the Marine 454 injectors. Those are around 100# @ 28 psi. Mine were Yellow/Black and not Green/Black though.

Wouldn't that be sweet FAST! Thanks! I'll have to do a part number search and I'll let you know. Greens...Reds...Blues...? I owned a "green" couch for 3 years only to learn it was "blue" when I went to sell it! Thanks again guys!
