You will at least have complications with the carbs. The 79 carbs were completely different than the 82. If I recall correctly, the spacing is different for the intakes on the cylinder head and they will not line up. :(

There is another thread here where a guy used offset carb boots to make it work. New carb boots are often a good idea after a few years anyways.

His thread is on engine heads and using a 79 head on an 82? engine.

thanks guys. my main concern was if i the motor will fit properly in the frame. as of right now i do not have the carbs for the 82 motor so either way i have to buy new carbs.
