    It didn't appear to be a radical modification.

    Truck still has stock pistons, heads, compression ratio.

    If the truck didn't ping with the mods and the tune and the power output he wanted, I would guess that 87 is enough.

    To put it simple I didn't want to change to 93 octane. I'm not running any boost and the Hot Rod cams are a direct replacement for stock cams. The stock valve train and VCT are still being used. After spending $75 in gas every 2 to 3 days in my Lightning I'm just not ready to do that in this truck. I am curious to see what kind of results I will get with 93 octane or E85 but that may come after the new intake goes on the truck.
    The only difference between the 5.4 and the 4.6 is the deck height once you get passed that its a lot easier to mod these things.
