Yes Mercury got the rods from Manley... Is there a reason you want to replace the bolts? If you want to upgrade from the ARP 8740's part # 42361-4 you can get the ARP 2000's #42249-4, but if you are looking to upgrade something I would spend that money on better vale train components, the rod bolts are not a weak link in that motor.

Thanks for the info. I am rebuilding the motor and up grading as much as I can. Crower stainless steel rockers, Isky 8005-A valves with 10* retainers and locks, heavier push rods, up grading all bolts with the better ARP stuff and whatever else I can do. Hopefully I will get several years of worry free service from them.
