I have a 1990 mustang gt with trick flow track heat intake, stock bottom end, vortech supercharger and upgrade fuel system(255lph and 42lb injectors). I just bought the gt40x heads and 1.6 rockers and waiting to get installed. If I go with the F cam do I need to notch or would it bolt right up? And also with these upgrades would I need to go bigger on fuel or am I still good?
Each car is going to be different so the only way to know is to actually have the cam and check ptv on it. Same with the fuel system, If you are running out of fuel with your current setup or have the injectors maxed out then yes you will have to upgrade it.
