I didn't do the math but yeah that's pretty big. Glad I did cover my butt and said when 1project2many says something I listen... In the end correct injector size, correct fuel pressure, correct CID in calculater will give correct BPC to start tuning.

here's a list of TBI injectors, note some 4.3L came with 2 differant size injectors and I don't know the size of them when differant.
