You can read most of the specs right off the spec sheet..... 1.01" CH, 443 grams.

They did lighten the skirts some internally, but they wanted to leave as much strength as possible since it hardly has any skirt length & a 1.40 R/S ratio. They could have been made little lighter, maybe into the high 420's but they'd be hand grenades.

We're using a 2.50" X .866" Tool steel pin, bobweight will be about lightest you could imagine for a 500 CID motor.

The rods just walked in the door on the UPS truck a few minutes ago. I'll have pics this evening of them, they are unreal.... the beam is scary looking.
