Im getting mentally prepared to reassemble the timing components on the 400 in my truck.

Wondering what the correct torque specs are on the Bolt that holds the large timing sprocket onto the cam,and what is the torque spec of the large harmonic balancer bolt.

I think the rest are pretty much gauged as "tight is tight" or "snug"(timing cover) or are there any other fasteners that need a special torque value when doing a timing Chain and gears?

The timing sprocket bolt should be installed with locktite. VERY IMPORTANT. I Torque mine to 30 ft/lbs. I haven't found any specs either, but then again, I DO have a MP engine book here somewhere. It may have the info you need. I'll respond if I can find it.

crank bolt 130 ft/lbs
