stated on a land rover frame. They used a 215 Buick V8 so it may be a nail head. I kind of like making cars into 4x4's. Not sure why they would in AZ except to run the desert
No the nail head GM motors used a reverse set up pushrod rocker arm set up so the valve covers mount on the engine in a flat method. If you ever see one they are easy to spot from then on.
