A friend brought over a box of tbi parts that were on his car before he bought it. The box came with the car. It had a holley projection system and an Accel gen 6 (I believe). I think this TBI was connected to the Accel system, but not positive.
It looks very similar to this Holley universal TBI but it has injectors in sides.
