You will notice that the wording realitive to ARP has been eliminated from the newer ad.
Also, thats a pretty ghetto way of spacing the girdle off the main caps. The picture shows 2 washers, a 12 point nut, another washer on top of the nut, then the girdle. The nuts look like Pro-Comp stuff. The pricing indicates the same.


I'm putting an engine together for a friend and he bought the mancicni girdle kit. Nice complete kit but same issue. The long main studs in the kit I am certain are not arp and to make things worse when torquing them down to measure the mains one snapped off. It appeared the hardening process was not right. Mancini said they would replace all the studs with arp but I don't know if they can due to proprietary rights of someone. There have been posts on here about trying to buy these studs direct from arp and they couldn't.
