Well I'm new to the Chevy life and must say it's nice but I have a 98 k2500 vortec 350 with a nv4500 trans an 4.10 gears all bone stock except for the front end and aftermarket sensors that have gone out over time. But I'm looking for a few ways to give this old truck a little more pep and to answer the obvious question yes I am rebuilding the motor.
