B18 / B20 weights

Hi again, Does anyone know what these engines weigh? i.e. block with flywheel & cylinder head, ancilleries removed. Also any idea what a g/box with o/d weighs? Any help much appreciated. Gordon

My green book gives engine "weight inc electrical equipment and carb" as 341lbs (B18A), cheers, Bill

...and I would estimate the weight of the gearbox plus overdrive, by comparison of its luggability with that of an AD1 with the flywheel off, at about 100lb, maybe a bit less.
