Hello Team, just bought a 67 Fastback Impala. It has the original 283 at 86K miles. I'm not a racer, nor strip dragger. If anything I'll take this car to a few car shows throughout the summer and to church a Sunday or two. Im not looking to really swap the engine. EVERYONE keeps telling me to do so, but what I want is just to get a nice muscle car sound from the car. Of course with doing that comes a tiny bit better performance, but Im not looking for a torque monster, nor the HP of a Hellcat. Just a cruiser that sounds really good, feels good and looks good. Any suggestions, again I don't want to swap the motor, Thanks.
