Packard Forum Index » Post-War (1946-54)

I agree with OD, the engine swap would significantly devalue the car as the 359 engine was a key feature of the '54 Seniors, and aside from the aluminum head were as reliable as any of the post war 8's. It was the most powerful flat head straight 8 ever put into a production car. 359's are getting scarce but not impossible to find. I have a few extras lying around.
