I just got my 454 tbi in the mail and it looks like the injector tower is not the original one that came with the tbi because of difference in appearence. I just wanna make sure that the injectors really are for a 454. I don't have time right now to read the numbers off the top of them cause I have to go to work, but I can later tonight if that's what its gonna take to indentify them. Thanks for any help
