REVIVING THE HEARTBEAT OF A SQUARE-BODY C-10
The popularity of square-body C-10s is growing, and they’re becoming more difficult to find. We’ve had our eye on a certain ’79 model that had been sitting in our friend’s backyard for about five years. When the time finally came for us to snatch it up, we were ready. The truck hasn’t run in all of that time, and it’s slowly been deteriorating. We did a little more research and discovered that the truck hadn’t been driven daily since 2000. We had our work cut out for us.
We’ll be documenting several steps in the revival of our '79 square-body, and we’ll start with getting the truck’s heartbeat pumping again. We did some research and learned that the truck was originally equipped with a six-cylinder, but it had been swapped out for a small-block 350-ci V-8. Since the 350 engine hasn’t run in at least five years, we knew that every seal and gasket would have deteriorated and would need to be replaced. We also decided that it would be a good idea to swap some of the factory parts for aftermarket versions to dress up the engine and add more horsepower.
Summit Racing was called upon to us get everything we needed to bring the engine back to life. Before getting our parts list together, we examined the current condition of our engine. We turned the engine over by hand, making sure it wasn’t locked up. Next, a compression test verified we had good internals, so we focused our Summit order on the outside of the engine. Follow along as we revive this square-body’s heartbeat.
