I couldn't help noticing some false statements and misleading advice that was followed in Travis' T150 Trident Project.
Conrod bolts are not one-time-use only.They do not stretch to yield when properly torqued.They stretch elastically,and return to their original length when you undo them.
It is safe to re-use them if you can torque them up without them yielding.You're not likely to reach full torque if they do yield.
Advising someone to "buy new rod bolts" can be dangerous.You're not likely to find original NOS bolts.You are likely to find inferior bolts,which are not even made from a forging.The original old rod bolts would be superior.
If you buy ARP rod bolts,there is no problem and you will get good bolts.In this case,follow their instuctions.You will need a micrometer to measure elastic stretch.
