Interesting, I have found the 127.8 mm GT3 rods to weigh around 450 and the 130 mm ones 424 grams w/bolts.

Yep, I have measured those connecting rods to be the same as you have measured. On the 130mm ones, there are different weight groups and I've seen them as heavy as 435grams with bolts. The 127.8mm connecting rods had ti bolts in the early ones and were lighter than 450g, but the later onese were heavier. The connecting rod in the pictures above was an old 130mm GT3 connecting rod I had around.
