Have run 560 lift in the stock magnum,no problem. Over
[email protected] must check and adjust ICL to get enough room. The Lunati lifters are Morel and no trouble with a magnum block. The 5.2 cam is still tiny and no big upgrade.

I'd skip the Oregon guys and go to someone that doesnt waste time trying to copy real cam designers. Yes.I have worked in real cam companies.
