I haven't weighed a set of rod bolts and nuts separately but they would be a factor also as the earlier rod bolts were heavier than the later ones. In fact, the reduced size of the Carrera rod bolts is one reason that it is recommended they be replaced with ARP or other aftermarket bolts.

Hi Fred,
Well, out of curiosity, I did also weigh the OE rod bolts yesterday as well. Strangely (to me at least) the stock bolts and nuts (used on the 965 rod) are 33gsm apiece. The ARP's are 34/35gsm each.
That did surprise me, as that chunky hex nut on the stock bolt looks far heftier than the beautifully made ARP multi-point nut. I guess the weight is in the ARP bolt itself?
