I have a '69 Mustang which is getting a new clutch. As such, I also pulled the flywheel and had it resurfaced. I also bought new flywheel bolts. The old bolts had some sealant or threadlocker on the threads. I'm more inclined to believe that it's sealant because the bolts use star-type lockwashers and are torqued to 75-85 ft-lbs. A threadlocker might be overkill. Is there anything that is recommended by Ford for coating the threads on the flywheel bolts on this '69 302?

Well, with a little homework on the internet, I got the answer. About.com has an article that prescribes the use of a Teflon-containing thread sealant on the bolt threads and a Mustang Monthly article prescribes the use of Loctite thread sealant. So there's the answer to the question. I hope maybe this information will be helpful to somebody.

All my hi-po engine builds get both, I would use both. No such thing as overkill on bolts that require 2-4 hours to get to
My 2 cents

Overkill or be killed.

Replace the rear crank seal while you are in there.
