Can you put a 3.8 out of Buick into Pontiac Grand Am?
No, you cannot directly put a 3.8L Buick V6 engine into a Pontiac Grand Am without significant modifications, and it's likely not feasible or cost-effective. While both are GM vehicles, the engine mounts, transmission compatibility, wiring harnesses, and other components are different enough to make it a major undertaking. You'd be looking at a custom engine swap, requiring extensive fabrication, custom parts, and potentially significant expertise in automotive mechanics.
