IM surprised by Richard Holdeners 360 Magnum camshaft swap.......

Factory cams are so ridiculously small, you can make a decent upgrade and add good power from the very bottom and gain a few hundred usable RPM up top. cam specs from my 97 5.9 magnum were 250/264 duration w/ 398/401 lift - similar to early LA 318 cams.

No doubt! In addition…. Cam size dependent, little to no loss of low end torque worth mentioning. Address the cylinder heads for better power no matter the cam size.

He’s using a set of 1 7/8 headers on that engine. I’m betting if he says anything he says they are 1 3/4. They are not.

He never mentions header size IIRC. He would get called out instantly by you and I right quick. I have 2 sets of those. IMO, a bit big for the test on hand. But, ya use what ya got.
