What's the torque specs for the one single 7/16 arp bolt for a fuild ati harmonic balancer. I been hearing all different stuff. Jegs/summit told me 60ft pds with a little red locktight... We already have it seated just need torque specs for that.. It's a single key crank design. 383 stroker with a vortech supercharger..... Just anyone please help --- Should I use locktight red or the blue stuff and torque specs??

 

I don't know the torque spec... mine was installed 11 years ago. But if you have a lot of boost, you need to reinforce the hub, and possibly add a second keyway. I've seen two high boost (20+psi) LT1's break the hub on the ATI Superdamper.
