HELP! Balancer bolt will not stay tight Recently finished our 427 stroker, pressed the underdrive pully on, tightend/torqued the new ARP balancer bolt, eveything seemed fined, 3 days later noticed the bolt was finger tight, so I retorqued it again, this time with RED locktight, 2 days later and about 25 miles, Yep bolt finger tight again, any ideas or reasons this is happening, or any advice on keeping it tight? Thanx

Did you let the locktight cure?

Shouldn't need loctite but I know many do use it. Did you check the pulley after install to make sure it was seated far enough on the crank by the GM spec?
As added insurance I pinned mine with the ATI kit so it wouldn't ever spin on the crank.

Yes It is seated correctly, I cleaned the bolt, and inside the crank with brake clean yesterday, re-locktighted the bolt, let the locktight set-up for 3 hrs, and torqued it to spec, so far so good.
