I'm running 16 BTDC. Pick up a can of "Seafoam", use as directed to restore c.i.'s of combustion chambers.

lol dfordski I thought you were linking one of those crazy gimmick plugs. Lining up the plugs to face the intake valve is a good idea, although somewhat difficult in these engines. Nitrous is quick and easy in many respects. It is quick and fairly easy to install as goes for the horsepower gains. It is also quick and easy to grenade your engine ;). If you're going to beef up your truck, you might look at getting the engine built. Hard parts are about the only thing that is going to get you anywhere past 400hp and keep you there reliably.
