5.9L Magnum questions

MechNerd said
As far as the cam goes, I think I'm going to go with an Oregon regrind. Here are the cams that Ken proposed- any benefit to one over another? Was looking for the same lope my buddy's 69 340 Dart used to have, and it wound up fast. Sadly, he's no longer with us, and I can't ask him if he upgraded or not. He did mention a Purple cam though. Not sure of specs.

Highly doubt there's gonna be a huge difference in power especially in the lower rpm bands, each cam gonna have probably a slightly higher peak hp over the one below it.

The biggest one is similar to Richards in that video except on a 110 instead of 114, he makes 350 hp at 5000 rpm and think he gains another 10-15 hp in another video with an air gap.
