Don't tell me your getting your advice from another forum, please tell me it's educated and/or experimental advice.
Good theory but you contradict yourself here. The bolt transfers the clamping and holding force, true. Yet you should know that ARP bolts require more torque, what's this do to the caps? It's stressing them ever so slightly. Ever heard of the term "out of round" on the big ends?
OK lads,
We know from our primitive instinct that a circle is one of the strongest shapes known to us, we try compress a circle shape, and it resists if being supported well, otherwise it will bow out and become an elipse. Lets say you get your ring, the type you wear on your finger, you try squeeze it. What happens? **** nothing. You put it in a vice, what happens? It becomes elongated in the perpendicular direction of the force, in otherwords, an elipse out the sides of no load. If you were to support the ring while in the vice so that it can't move, and apply the force, what happens? It will try buckle, yes? We just proved that the shape failed and bowed out the sides, so why won't the ring deform in another way?
That is exactly what's happening when you install ARP rod bolts into a standard rod, maybe you get lucky and you won't need to close and hone the big ends, sure, plenty of people do it, but plenty of people don't service cars, sit on the limiter all day, don't warm their cars up, yadadyadad. Alot of other people will have another opinion on installing rod bolts too from their experiance, but it's not the right way to do things.
If you want to uprate the rod bolts, pull the rod out, torque it to spec and perform the required machining, if any.
