At some point in this cars life, someone got into this engine and found it necessary to replace some pushrods. So they went to the local auto parts store and bought over the counter replacements. Coulda been decades ago. The balls and sockets don't quite match the factory originals. But so what? As long as they are the correct length and roll flat on a tabletop, the engine will never know the difference. He said he's looking for a few months service before replacing it with a v-8. It's not like this is an 8 second high rev SS car. It's a slant six lucky to see 4000 rpm!
