63 Lemans 326 Piston weight
 

I'm finally getting ready to build up my 389 with a 1963 Tempest/Lemans 326 crank with the bolt holes for the "rope" shaft. I need to know the weight of a stock "336" piston and pin, so I know what reciprocation weight to shoot for when I have it balanced. I got this info from someone several years ago and put it away so I wouldn't lose it...which I did. If memory serves correct, it wasn't too different from a 400 TRW piston I had laying around, but I still want to know for sure before I select a piston, pin, and rod combo and have the block bored out.
I know they can remove weight from the crank, but I would prefer not to have to pay for "mallory" to be added to compensate for a heavier piston/pin.
Thanks,
JK
