Multiple Torque Specs.
Hi guys, After searching through 8 pages and finding little, ive decided to post. Im putting my 390 motor back together and need torque and bolt sequences for the timing chain cover, oil pan, and intake manifold. Does anyone have a link to diagrams and specs for these?

Intake is 40-45 ft/lbs, start in the middle, and work your way out. Start at 20, work all the way out, then redo to 40-45.
For the rest, I can't find a bloody thing.

Edmist –
I found these specs listed below from the web years ago. I don’t know if they are completely accurate as I used the recommendations from Steve Christ’s book (I don’t have it in front of me to compare). I am sure someone will correct the specs listed below if they look off.
