    I hope so because I just finished my install and when I took the truck to the shop to have some other adjustments made they said that the projection TBI system was pushing too much fuel for my engine. I know that the Projection has an adjustable fuel pressure so I could just turn that down right? The holley specs are for a chrysler, GM or ford V8. I assume that if I adjust the fuel pressure way down, I should be fine.

    Tough call. I'd expect if the TBI injectors on the Projection are enough to feed a 454 (what does holley say about that?) that would be too much for a 305. However, since people go with 454 injectors on 350's, a 350 injector (one that won't support the 454) might very well be fine on a 305.

    It is for a max hp of 270, and the fuel output is adjustable. I will just have to install the air fuel ratio monitor in order to tune the system.
