Technically, according to a scan of the orig. chip programming it is 23.8lbs. Now I think where the confusion comes in is this. Factory injectors are rated at 24 (23.8) lbs but this is at 43psi pressure. When using an aftermarket injector such as the ford svo injectors, they are 24lbs but at 38-39lbs pressure. So at the set pressure of 43 they are more around 26lbs give or take a little.

Buy Ford (Bosch) blue-top 24# injectors. '93 was one of those years when they used some brand (I can't remember the name), that just weren't that good (but better than Accel). Do an internet search and find the best price (you don't need the overpriced "matched" set).

I run LS6 injectors. At my LT1's stock pressure, they are supposed to be around 25.8#, if memory serves. If I were to boost the pressure to LS6 specs, they'd be 28# injectors.
