Waiting on another rear main seal set, the first one I ordered was lacking the two short little seals that sit vertical on the rear main cap. Ideas about where to find those welcomed btw.
Thought I would try for a conscise conversation and assembly a reference list of torque specs.
From the bottom up:
Mains: 120lbs??? (I think I heard that in a military chevy video)
Rod caps: 80?
Oil pump: ?
Oil pan:?
Flywheel:?
Clutch disk:?
Bell housing:?
Heads:?
Intake:?
Valve covers:?
Carb:?
Water pump assem:?
Pertinent others I'm omitting???

Alot of this stuff doesn't actually HAVE to be torque to spec.
According to the book:
Mains at 130-140 ft pounds. I did 135.
Be sure to torque the two rear main 1/2 inch cap bolts at 55-65. I did 60.
Rods at 55-65 ft pounds. I did 60.
Oil pump I did Tight because I didn't know the spec(No book at the time).
Oil Pan 10-15 I'd say, If you use a good gasket and gasket maker.
Flywheel bolts at 100 ft pounds.
Heads 65-72. I did 70.
The clutch pressure plate bolts I'd say no more than 35 foot pounds as they are small and can snap easily. But since someone below makes it a huge issue, be sure to find the correct spec. Truth be told....I have never actually torqued those and have never had a problem. But there is always a first time.
Bell housing 50-60.
Intake 20-25. I didn't calculate when I did mine.
Valve covers. I snugged mine down. They don't need to be Sinched.
Carb. I also snug the bolts down on those in an even order.
