I notice in my 1951 truck shop manual, all the torque specifications for assembling the engine are listed in tables. I can't find this information for my 38. There is one mention of the head bolt torque values and that is it. Where are they listed?

I don't think they are published, I go by this:

Thanks for the link. I find it interesting that they didn't include the numbers in the manual like they did in later years. I think there is one big change around 1953 with the new head, I think the torque went up some.

I would assume the torque spec's you can find for any old 216 are good for any old 216. laugh

Remember...Torque specifications don't have to be followed.
They are recommended to keep big strong egomaniacs from..#1 OVER TIGHTING and breaking off the bolts..#2 trying to maintain a consistency so all the bolts are tightened somewhat equally as not to warp the part that is being torqued...ED


I was only wrong one time in my life so far. But that time I was right, and only thought I was wrong....ED

That's right ED...Back when men were men you didn't need no stinking torque wrench... laugh
Actually, if you do much wrenching you get a feel for what's "about right"...And the biggest problem can be over-tightening and it's consequences...

Here are some links:
http://www.1954advance-design.com/Stovebolt-engine/head-bolt.html
On this one, go to p.28; it says 75-80 lbs. for head bolts:

And one more:

Hope this helps.
