If you put an 0360 and an 0320 on a scales, with both fitted the same like basic engine and a carb, how much heavier is the 0360 going to be? Someone said the carb on a 0360 is heavier as is the crank and cylinders too. Anything else that is heavier? Are the pistons the same diameter? I know the stroke in the 0360 is longer. I am considering selling my 160 hp and putting in the 180 hp but I don't want to gain much weight. To me much weight is like 10 lbs. And on the nose is double trouble. Right now I don't have a starter or alternator up front or starter right to save weight. I know the prop is heavier for a 180 but I am not concerned with that right now. I just want to know what the exact weight difference is for the engines and carbs.
