No, you cannot use just any carburetor on a 1987 Chevy Caprice. The 1987 Caprice, depending on the engine (likely a TBI-equipped 5.0L or 5.7L), was equipped with
Throttle Body Injection (TBI), not a carburetor. Trying to install a carburetor would require a significant and complex engine modification, and it likely wouldn't be practical or reliable. You'd need to replace significant components beyond just the intake manifold.
If your Caprice has a problem with its TBI system, you'll need to either repair or replace the TBI components or potentially upgrade to a different fuel injection system (though that's a very involved project). Simply swapping in a carburetor isn't a feasible option.
