High gearing will create less top in, so you burn through your gears much much quicker and get off the line quicker but can't run as fast.

I'm not an expert though

not enough top end power for that steep of a gear.

He's right, with the 4.8, you probably don't have enough power for that gear ratio.

Yeah 4:56 are a lil much, the 4:10s seem to work really for the 1/4. I bet she is wound out on the highway with those gears.

4.10s and a nice cam should do your truck right

In your case those gears are best for 1/8 mile. All things considered... just my .02 cents
