          it will fit, but if you don't change the heads the intake ports won't line up correctly.

              all the fuel injection 2.8,3.1,3.4 iron heads are the same.

              candychevy87, if you are talking about putting the intake in a s-10 then it will have to be rewired they have 6 injectors, but can be done easy

                  Yea the post is kind of vague. I am not exactly sure what engine year or vehicle he is referring to. But I am 90% sure he was talking about an iron head 2.8L

                          If your trying to run SFI in your S-10 then yes you need to change all the wiring and the ECM.
