Cam & head upgrade 360 mag

For a truck I'd consider a 408 (or larger). Low speed toque is a must for heavy trucks. I went from a 351m to a 460 in my F-150 and the low speed torque is awesome. I no longer have rev it to 4K to pull a grade or even just to get the damn thing to scatter it's own poop. All that a cam will do is shift your RPM band higher, and you'll need a converter and gears.
