Im in need of some help, i have a 94 f150 4x4 with the 5.0 HO. I recently did a gt40p head swap as well as rebuilt the motor and installed an e303 cam. The truck starts and runs but has a few problems. It tachs about 4000 rpms on first start, but gradually drops to an idle. Does anything else need to be changed/adjusted? I am running the stock upper and lower intake. Any help would be much appreciated. Thanks
