I would bet that if you look close and run some numbers on that motor you will find that it has powerpac heads on it. If they are that means you have 60cc combustion chamers. The valves are kind of small in these heads but if you put a beter intake, carb and headers you will find a noticible difference in performance. I would also recommend going with an HEI and an internal voltage alternator/regulator. The 283 was a great little motor with a lot of rev potential. I would keep it. For about 600 dollars you could have a respectable motor. All of this depends on how solid the bottom end of the motor is. Are you burning any oil or hearing any knocks?
