Two versions of 4.9.
The economy 4.9 has a different cam and was equipped on trucks with the 2.75 or 3.08 rear axle ratio. It had 145 horsepower and 265 foot pounds of torque.
The standard 4.9 was on trucks with 3.55 gears or higher numerically. It had 150 horsepower and 260 foot pounds of torque.

Check the VIN label in the driver's door jam. Look for the axle code. Your factory rear differential ratio will determine what 4.9 you have.
The ECO 4.9 has less overlap of the intake and exhaust cam lobes--to make up for the high axle ratio of 2.75 or 3.08.

What about the 5.0L? I didnt want to make a whole new thread for it so i posted in here. The only add ons I have are a K&N CAI and stock exhaust all the way back to the muffler which is a Flowmaster 40 (1-in/2-out) which might be changing to a Cherrybomb Extreme or Elite.
Thanks
