I just got my first square body, an ‘85 K10. The previous owner did a 5.3 swap with an Edelbrock intake, Holley carb, MSD ignition, torkinator cam, new pushrods, valve springs, rocker arms, lifters, head gaskets, timing chain, headers…and a bunch of other stuff.

The truck runs great, but it’s the only K10 I’ve experienced. Here are two videos, curious if anything sounds off…the Holley fuel pump is loud as hell
