What is the best place to get remanufactured, matched , and flow tested Chevy TBI 7.4L Injectors from. I am looking for the Dark Red/Dark Blue 85-90# injectors, part#17112506 (if that is correct for that color code). I have visited Fiveomotorsports and they have them at a reasonable price, but I want to know if they are a quality company. Thanks for any info.
