Newby Overhauling a 283

[Toshab]

I'm a new one to the forum and to the world of classic pick-ups. Last year I bought a 1967 C10 with a 283 and 4 speed on the floor.

When I bought it the engine knocked pretty hard. I quickly put an HEI on it and intended to start a rebuild on the motor soon after. However, life got in the way and I'm just now getting to it. My goal is to get my '67 in a condition where I can roll down the highway at a comfortable speed.

I have a mechanic friend who told me the knock was a piston knock. He's itching to get inside my hood and do it all on his own, but I told him he can work on my wife's car, but this baby was mine.

I have some experience working on motors, but not just a whole lot, so I need some help from you pros out there.

What causes the piston knock and what will I need to look for to fix this? Also, what recommendations do you have to help me get this beauty running like she deserves?
