I ordered a set of injectors off ebay that are from a 03 vette. The seller said they would work in an lt1. I have a 93 and they are considerably shorter that the stock injectors. I had a friend machine the under side of my fuel rails where they bolt down to try to compensate for the shorter injectors they're still too short. The part numbers on the injectors are BOSCH part #0 280 155 931 -GM part#12561462. Are any of you guys running the later injectors in an lt1 and if so, how did you get em to work? Please give me any suggestions. Gotta get the car running rod run is in less than a month!

I'm not sure why you chose those, I would have gotten SVO or stock replacement if yours were bad. LS1 cars run about 17# more fuel pressure than LT1 cars do, so its not really an upgrade when you do the math.

Good luck whatever you decide to do.
