Catalogs

On page 27 of the Icon catalog it says the wrist pin for the IC745 piston is 0.984” x 2.75” and weighs 118 grams. On page 1 just below the table of contents the catalog shows light weight tool steel wrist pins. R-73 is listed as 0.984” x 2.75” and weighs 107 grams. That’s 11 grams lighter than the wrist pin that comes with the IC745 piston. Wouldn’t that be close enough to not have to rebalance or am I overlooking something?
