No, you can't directly put a 1970 Camaro front end onto a 1980 Camaro without significant custom fabrication. The body structures are completely different. The 1970 Camaro has a much smaller, more sharply angled front end, while the 1980 Camaro is much larger and more boxy. The fenders, hood, grille, headlights, and all supporting structures are incompatible.
While some individual parts *might* be adaptable with extensive modification (like perhaps using some of the 1970 headlight buckets as inspiration for custom housings), a complete swap would require an enormous amount of custom metalwork, fiberglassing, and likely chassis modifications. It's a project far beyond a simple bolt-on swap.
