first i think on us820's you need to use nothing but the best bolt available .
on us820's con rod failures are historically the biggest issue with them.
using the better bolt sold by dave while expensive is still cheaper than a new motor.
no slam against india but i'll be using holochrome with this new information.
the casual attitude companies outside the usa about maintaining specs concerns me.
on their usefulness we've had nearly 8 years of testing at this point so a post update would be nice.
i'd love to see Scott update this post with his current experience.
if he doesn't jump in soon i may just bug him with a phone call and ask him to comment!!
finally,
in my experience unless you're building crazy stressed mccullochs the holochrome was working reliably on the standard motors.
using a torque wrench and not over torquing the bolts is critical.
also tossing the bolts after single use is prudent.
while they are being pulled super hard at 85-90 inch pounds they have the possibility of being stretched.
to me re-using a fifty cent bolt that might be compromised is beyond foolish.
