Thought I'd update this one too...
I wasn't able to go with 440 Source pistons (they don't make dished pistons, which I needed for my build) but I DID pick up a set of their Platinum Series rods.
These things are nice. Matched set all weighing in at 761 grams. 7/16 ARP 8740 bolts, etc.
PLUS their shipping is insane... I ordered the parts yesterday @ 3:00pm PST and they were delivered via FedEx today at noon. So approx 21 hrs total. And it was free shipping.
Assuming the rods don't fail, (nervous laugh lol) big thumbs up to 440 Source!
