How much heavier is an 0360 over an 0320, exactly?

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.

How much heavier is an 0360 over an 0320, exactly?

I weighed my PA-12 on scales right before removing the O-320 & installing the O-360 & then reweighed. The O-360 setup weighed 35 lbs more. Besides the engine & carb, also changed the cowling, prop, engine mount, baffles, exhaust. Light-weight starter & alternator remained the same.
