[QUOTE="Bean, post: 176742, member: 318"] Rod failures are happening at anywhere from 600-1000hp. Yes there are some that are running fine at 800hp without problems but that doesnt mean you can go out and twin one and expect nothing to happen. 600hp and down, would not be scared at all to run a 6.7 there. 600-800, getting into the brink zone could be fine could chuck a rod. 800+ its only a matter of time. Differance is there are plenty of 1000hp 5.9's on 12v rods that do not break rods. You wont find many 6.7's doing that without billets. [/QUOTE]
