Is this 1969 impala worth more since it has 325 horsepower?

The horsepower of a 1969 Impala significantly impacts its value, but it's not the only factor. A 325 horsepower engine (likely a big-block, possibly a 427) is desirable and *does* increase the car's worth compared to a lower-horsepower Impala. However, several other things heavily influence the final price:

* Condition: The overall condition (rust, paint, interior, mechanicals) is paramount. A pristine, numbers-matching, highly original 325hp Impala will be worth far more than a rusty, poorly-restored one, even with the same engine.

* Originality: A completely original car, especially with documented history, commands a premium. Modifications, even if well-done, typically reduce value unless they're very sought-after period-correct modifications.

* Documentation: Service records, original paperwork, and provenance significantly impact value.

* Specific Model: Even within the Impala line, there are variations (SS, Custom Coupe, convertible, etc.) that affect price. A 325hp SS convertible will be much more valuable than a 325hp 4-door sedan.

* Market Demand: The current collector car market fluctuates. What a car was worth last year might not be the same today.

In short: Yes, the 325hp engine makes the 1969 Impala *more* valuable, but its value is determined by the interplay of all these factors. To get a true estimate of its worth, you'd need to have it appraised by a classic car specialist or consult resources like Hagerty Valuation Tools or similar online resources that account for all these variables.
