I understand the importance of rod bolts and head studs in a boosted application. I'm just not sure what is gained with arp main studs. More clamping force to reduce the potential to spin a main bearing? I don't really hear of that happening much at all with these motors.

Yeah I think you’d be fine. If you don’t upgrade the wrist pins, you may want to ask your machinist to check the pin clearance. At that power the standard pins may flex a little more so a little more clearance would be good. A lot of forged rods and pistons come in at about .009ish so I like to open them up to about .0012”.

Billet Main Caps Hi 8R, MY REASON to fit ARP Main Studs is ONLY when I KNOW the engine will be rebuilt often AND then most often I also fit Steel Main CAPS.
Mostly due to costs involved, the Align Hone, stud kit = $500.00 with the Steel mains another $500.00.
YOUR question of power has seen the Powdered Mains CRACK (rear) over 1000 WHP.
I would ADD the MAX Torque of 80.lbs NOT 100 as in some ARP Tech notes !
