injector question

bio-brad said:

my 97 has 205,000 miles on it, I think it has AB injectors. I bought AA with 85,000 on them. Will these work in my truck? I'm thinking about diy stage1's in the spring. Should I use the AB's if the tolerances are good and save the AA's for a rainy day or possiable stage2's in the future or just use the AA's? I'm also thinking about doing a 17*hpop upgrade. What year 7.3's are these on and is it worth it?

I'm thinking ab s are the 120cc splits only on the cali models, don't know for a fact though. If you have single shots the aa will be fine. If you have splits now you will need different programming to run the splits properly I think. The only was you would have splits in a 97 though is if its a cali. Easy ways to tell is the fuel pump has a big pulsation damper on it making it look like the starship enterprise(no joke, really does). And the sticker on the rh valve covers of the cali models has a blue background instead of black. Being in michigan its possible for you to have a cali truck, but unlikely.
