Loctite on clutch/flywheel bolts

I didn't put Loctite on the clutch or flywheel bolts when I did the 4-speed swap on my Challenger not too long ago. It's just an internally stock 360. It has a McLeod steel flywheel, Hays 10.5 street/strip, and all the bolts are new. Should I be worried?

They are new MP bolts and yes they were torqued to specs.

Were they the original bolts? May have a little TL left in the threads. Did you at least torque them to spec? IF they start to loosen you may hear "knock" or vibrate at idle.
I know loose converter bolts sound like the crank is going to fall out at idle

Like the Fram ad, pay me now or pay me later.
How much damage will it cause if it comes out at high rpm.

I have never used Loctite on flywheel/pressure plate bolts in 25 years on street cars. As long as you torqued them to specs, don't worry at all.

The last answer is correct. Torque to spec, forget about the Loctite, unless it is called for in the factory service manual.

I agree, torque to spec and don't worry.
Although I still use loc tite.
Blue for piece of mind and red for the serious stuff.

You makes your choices and you takes your chances.
Built a motor used new performance bolts torqued to spec. About amonth later flywheel came loose shifting @ 6000 rpm. Didn't come off the crank just started knocking like hell. Tore most of the motor down before I found the problem.

Now I use Loctite...
