Hypothetically speaking, if I put an engine like what I described above, wouldn't it only need to pass smog if said motor looked externally identical to the original 305? I mean, if I am being serious about following emissions laws for a engine swap, hypothetically speaking of course, I might as well scrap the idea entirely, rebuild the original 305 and have nothing close to what I intended to drive, right? I may be wrong, but it would seem like lifting out a LS set up would be just as unlikely to pass a referee inspection since it is not an engine that went with a Monte Carlo, or one of that year for that matter. I would love to do that, it just seems easier to go the 350 route, especiallt since that would be my preferred engine anyway, or am I way off?
