273 dilemma

My son does not have a picture of the 273 wrist pins but has notes of when he weighted them.

Full floating without the keepers they are 320 grams each. Not sure how much the keepers weigh. 5.64 POUNDS for all 8

The Light weight ones he got for his 318 were from Manley and are Pressed In and are 117 grams. 2.06 pounds for all 8

Easy to see the weight that you can remove from the crank. Even more if you do some work on the rods.

More too if you do some grinding on the crank like what David Visard did for the 318 Uncle Toni engine. End up with a much lighter rotational mass and less windage too.
