TRW piston L2373

Just purely for interest..... did you know that the 318 and both 273 type piston + pin weights were all the same? The Mopar engineers put some REEEEEALLY heavy pins in the 273's so that the piston+pin weights stayed constant for all 3 engines: 318, 273 2 BBL, and 273 4 BBL. The 273 2 BBL pins weigh 220 grams each! The cranks all balanced out to the same bobweight this way. Talk about long-term planning.....!
