[Backtobasics]

I vote for a couple "performance" type upgrades, to give a little more torque. Air Intake, Exhaust, Headers, as previously mentioned. Let the thing Breathe. I believe a throttle body spacer is available for this too. This should give a little more torque, so less throttle is needed to get moving. Keep the 4.10 to help umph off the line.

Be cautious of the fuel level getting to E. The moden cars use the fuel for cooling, so 1/4 and less poses the higher risk of fuel pump over heating and wear. All your MPG go right out the window when replacing electric, high pressure in tank pumps, which equal hundreds of dollars, plus labor, if applicable.
