cam swap
Yes, But only on the earlier versions, non magnum as they have the same size brgs. The magnum engines have a larger size journal and would require a custom cam, as I'm not sure if anyone is building a performance cam for them yet. But then you would have to look at the cost effectiveness of what your trying to do. Also you would have to change the pushrods as the lifters are shorter, to the nonmagnum style.
