Not sure what you’re asking, but I think your question is about a 350 made in Mexico(?). GM shifted production of some of their replacement engines (TargetMasters maybe) south of the border in the ‘80s. Goodwrench became the name later. I think they’re basic, mild compression, mild cam service replacements that serve well but not excitingly.
