They should be torqued to 250 ft lbs, but are more frequently not. The result if left too loose, the hub will spin on the crank snout. The bolt torque is what holds the hub in place, not the interference fit over the crank snout.
The hub is less than $100, but the crank would have to be removed and repaired if excessively damaged. Most times, they just ruin the hub.
This is sort of a public service announcement. We're starting to see more people buy the crank pin kits because their stock engine spun the hub. Under warranty, no problem. Out of warranty, check it as routine maintenance.

PS to Dodge;
Please take 20 minutes and have one of the engineers modify the crank drawing to use a left hand threaded bolt for the crank snout / hub. Remember years ago when you used left and right hand threaded studs on the wheels depending on which side of the car they were on? We know you can do it
