A K10 has too much rotational inertia to ever be a drag racer....especially if it has the granny low 4 speed. However, it can be peppy.

I don't want it to be a drag racer but make it where it will get out of its own way. It has 35's and a 4" lift so it is never going to be really fast. I figured add some vortec heads, intake, cam, and headders and it should run all right.
Thanks for the info
