Nice to see that the powers that be aren't making 273s run the extra heavy pin that was stock in the 273. Also rod minimum weight is some 60 grams lighter than stock.

Yep, 90g minimum. I don't know if anyone makes pins that light unless they were titanium. I think Chrysler made the extra heavy pins for the 273 to have the same weight as the 318 piston and pin.
