I?m working on my 54 Hudson Jet 202 ci L6 I?m trying to find a piston for this engine. The #6 piston has a small chunk missing from the outter edge. I?m trying to figure out if other Hudson engines have interchangeable pistons. I?ve read that the 212 -6 and the 254-8 all have 3? bore like the 202 Any input would be greatly appreciated
