    3.4 injectors on a 3.1 hydrid

    Will 3.4 injectors from a push rod 3.4 work well on a hybrid 3.1 with a Crane 2030 with stock heads and exhaust (Fiero) and 56mm TBI?

    the 19# injectors should be fine, just have to tune for them...

          When you state "tune for them" what do you mean exactly? And would the 2.8 injectors work just as well?

          (Thanks for the reply)
