Hey guys.

Im hoping somebody can answer my question. First off I have a stock 1989 5.0. I am planning on getting a set of GT40 heads and possibly a cobra intake. I was also think I would do some roller rocker work on the GT40's for a school project. Would I need to upgrade anything else to go along with this? Like the fuel pump or anything like that?


Thank you! Hope you can help me.

so you want to do the cobra intake, gt40 heads and a cam? I am not positive if its absolutely neccessary but I would switch to 24lb injectors and a bigger fuel pump just to be safe. And I think with the 24lb injectors you will need a different mass air flow sensor that is calibrated for that size injector.

If you do the cam i would upgrade the injectors and the MAF but if you dont do a cam dont bother wth the injectors.
