okay, it's time to upgrade options. I want the most power out of my 3.8 going naturally aspirated. I heard a 4.2/4.3 is a great way to add power. What's the highest compression ratio I can do? What if I got a 4.2 from an f150? What year do I get it from? What's the best sounding cam with the most bang for the buck? springs? torque converter? transmission mods to go with it while the engine's out? I could use any help possible.
