Default Torque Spec Question

All,
I'm hoping someone can confirm the torque spec for the bolt that holds the alternator brace (bracket) to the block (water pump). The AIM calls for 20-30 IN PNDS. That doesn't sound right. The 66 shop manual calls for 30 FT PNDS for water pump bolts. Is that a typo in the AIM? Can someone confirm please.
Thanks in advance

Rob, It's got to be a typo, a 3/8 course bolt has a torque spec of 30-35 ft lbs.

I use SNUG TIGHT - the full effort of a normal size man on a standard wrench. It is getting hard for me to qualify as a normal size man. but it takes full effort sometimes to get up off the couch?
CAUTION: If using a split lock washer, tighten the bolt only until the washer is completely collapsed. Over tightening even with a torque wrench will deform the lock washer and reduce it's effectiveness.

My 72 shows foot pounds. I'm sure it's the same for your 66.

Thank you all. The 72 AIM looks almost exactly the same as my 66 ... other than the typo.
