I have a 67 Grand Parisienne in my yard that came factory stock with a 327/t350 combo. The motor is out so it will be easy to check the difference between the frame mounts and motor mounts. You have to remember putting that sbc in your bird will devalue your car somewhat. It would be more fun and value added to go with a 455 if your looking for more power. Either way hang on to the 350 that came with the car originally. (If it's a 6 cylinder car definitely leave it as is and find a Camaro, Mustang or Mopar to thrash.) I'll post pics of the mounts later. About to paint more parts and will need something to do other then watch paint dry.
