Anybody out there know what the torque specs on the damper plate screws are for a 351/powerslot? I read on another thread that it was 35 ft/pounds but that already snapped 1 bolt. Is that correct?

I cleared out a place in my PM inbox.

This manual is for models 70C & 71C

If you don't see the specs in there (which I do not for the 3/4' long bolt), I'd tighten snug with an additional pinch and live with it. Or I'd consider a consistent lesser value, say 15 -17 ft-lbs. Thirty five is a lot on that bolt.

Thanks cloaked. I have a manual for 71C & 72C and I didn't see it in there either.

These are the bolts. I actually went up to lowes to see if I could get a replacement. They didnt have shouldered bolts and the size of the bolt was in between 3/4 and 1 long. 35ft/lb broke the grade 8 replacement also.

At that point I figured 35 was either too high or my torque wrench was way out.

And yes, that is $5 a piece for the bolt :)

It's been fun bringing her back to glory. A little frustrating at points cause I am missing days on the lake with my family, but I know its necessary. Fortunately, Florida has a pretty long summer.

And I can not adequately express my appreciation to you and all the other TT'ers for the guidance/knowledge. Amazing!!
