My son has a 2006 Dodge Ram 1500 with the 5.7 Hemi that most likely has a blown head gasket that he's looking to sell as is but neither of us have any idea of what it's worth. The truck is in good mechanical shape other than the issue with the Hemi and the only real body damage is on the edge of the drivers side door where the wind jerked it out of his wifes hand at the gas station and it hit the concrete by the end of the pumps. It's been sitting for over a year but it would start and run when he parked it.
Any estimates of value will be appreciated.

What tha? Man Hemi’s are a dime a dozen now. Slap a new one in there and bawl the tires off it!

He just doesn't want to mess with it. The 5.7's should be a dime a dozen with all of their issues. Slapping another one in there is for someone else to do.
