No wonder the '68-'69 higher compression 318s perform so well and have more available power. Huge difference in weight there, 30 oz.

That is getting close to 2 lbs less reciprocating weight with the 782 lighter rods.

30 ounces =850+ grams. That would be over 100 grams lighter per rod. That is not correct. 10-15 grams per rod is more like it.
