Neutral balance to a 360 crank?

I'm pretty sure that 273 rods are heavier than Eagle SIR & Scat I beams. For reference, 360 +.030" flattops by Probe are advertised at 476 grams, SRP flattops are advertised at 489 grams, Ross is 484 grams - lighter than any other off-the-shelf pistons I've been able to find, forged or hyper.

I don't remember. I used to know. I do know Mopar Performance offered a reman version of them that was REAL nice. ARP rod bolts, cintered bronze bushings. They were sought after for a while. They're still a "good bit" lighter than the standard 340/360 rods.
