So my 96 5.0 is getting pretty tired and it' time for a rebuild, but since it's my daily driver I am looking to buy another motor to build and swap in to minimize downtime. The question I have is what problems will I run into if I get a later model 5.0 to build? Ideally I'd like to find another 96 to build but I'm having a hard time finding one. I already have torque monster headers for the gt40 heads. If I used one with gt40p heads could I delete the egr so the headers would still work? Do the later models require more fuel pressure? I' going to get a differet cam to put in for the build as well. If I have the cylinders bored slightly over will I need different balancers? This is going to be my first engine build so I don't know much. What is a good book to get for building the motor? I eventually plan to make the truck off road only but will be continuing to dd the truck for a while before hand, what other mods should I look into when building the motor?
