360 out of a 1977 RV

If the engine is untouched then the cam is the standard .410/.412 lift with 252/256 duration used in all 2bbl 360's.
LD 360 2bbls. There were 360 2bbls used in Super Coupes and towing package cars that got a different cam, I think it was the E58 cam those got. But on your truck and van donors that shouldn't be something that exists.
