Hi, I wanted to install an original 66 A code cast iron intake manifold and 66 A code 4100 autolite on my 66 289 tonight (carb was rebuilt and intake manifold looks solid).

Also, I have 66 HIPO valve covers I want to install...

I don't have torque specs for either... can someone post them up for me.

Thanks!

Intake Manifold to cyl head 14-16

Buy yourself a shop manual.

One thing to remember is that engineers don't pull bolt sizes out of thin air. They know what clamping force they need. Therefore most 1/4" bolt of similar grade and going into similar materials will torque to the same specs. Same for 5/16" and so on. I.e. look at the bolt diameter and you will have a very close idea of the torque required. Fasteners are much more interesting that they appear. A bit of reading about their design and application will go far in this hobby. For instance some people use lock-washers everywhere out of habit. But you don't see them on rod bolds, do you? There is as severe an application as there is. There is a reason why none are used.
