Which motor would be a better choice if i was shooting for 300 whp and just as much torque ? I want to keep it N/A , Im open to head swaps , cams and bolt-ons . At the moment im leaning more towards the 5.0 for its larger displacement and ohv design . Would a new cam , longtubes , ORY , and cat-back get me to my goals with a 5.0 ? What would i have to do to a 4.6 to get those kinds of numbers ?
