i re-read the post and what another buddy i just got off the phone with, says that he was told when talking about magnum cams with cam companies, you should use a 5.2 cam in a 5.9 as it will make more power and torque than the stock 5.9 cam.
I could be wrong, but I think that info is based on wrong documentation put out by the factory. The 5.9 Magnum was released in ‘93, the year after the 5.2 Magnum. So, the factory documentation for ‘92 still had the old LA 360 info along side the updated 5.2 Magnum info and when the 5.9 Magnum came out the following year, I think the factory forgot to update it and carried forward the old broomstick cam info.
To further demonstrate this, I had a cam reground by Bullet Cams and asked them to send me the original specs first. The info they sent showed a cam larger than the 5.2 specs I have found. I have posted my info before, but don’t have it handy right now.
Not saying I am certain, but just makes no sense that the cam in a 5.9 would be smaller. And based on the above, I thinking it is a wife’s tail that it is.
