Sorry to jump in here, but ALL the LA engines (273, 318, 340, 360) had
the same length rod of 6.123" center to center. The 273, 318 and 340
had the same stroke of 3.31", the 360 had a stroke of 3.58". The
340/360 rod weighed 758 grams, the 318 rod weighed 726 grams.
Info from Mopar Engines Book P4349340 copywrite 1984.
