FWIW; Mark Jones is the real deal guys, he's not BS'ing when he tells you what his stuff runs. Mark is a master at making absolutely silly power using seemingly mundane parts. He's also a master at making the entire vehicle he's working with as efficient as possible to turn in the quickest...- Vintage Musclecar

Rear end swap: Dana 70HD to 14 bolt
Still researching all this and found the following video: It appears the 3.07 Dodge ratio "can" be installed in a 70HD, but it's far from a bolt together affair.

FNG saying hi
New guy from SW Ohio (near Dayton) saying hi. Please pardon the seemingly unfitting user name, it's the screen name I go by on all of the car forums I participate on. (I restore parts for classic musclecars for a living, hence the screen name) I've owned a couple of square bodies over the...- Vintage Musclecar
