The books don't say, and Google references are scarce. Any recommendations for a torque number? I have an idea, but I'd like the opinion of more experienced folks. We're talking about the bolts here, not the brass screws.

Starting at about 21 minutes into this video, Mike recommends 30 ft-lbs. :-)

this is a pretty good guide for maximum torque by grade of bolt and is what I use

I really would take a less-is-better approach for fear of cracking a magnet. However, that doesn't mean loose. Just maybe go to the low end of the scale. 25 - 30 ft-lbs. maybe. And, of course, wire them.

Only the earlier magnet retaining bolts were wired - Ford deleted the drilled bolt heads & wire in later years.

Been a while, but don't we peen the ends of the magnet bolts that come through the flywheel?

It's the brass screws that get mashed on the other side, not the bolts.

As far as I know or at least according to Mike Bender, there is no torque needed for those bolts...just snug them down (if I had to pick a number, maybe 20 to 25 ft lbs,...or as they'd say in the book (and Bender put it)..."a good pull on the wrench" watch his video..."engine 14 and 15", he'll tell you)...they are spinning so close to the center of the centrifugal force they are unaffected by it....the further you get from the center that changes rather dramatically. :-)
