Safe max RPM for bone stock 5.9 magnum

(I think he knows it’s not a LA 360….)
I don’t know the head flow values between the Magnum and Vortec’s. Have a link? I’d say there on par with each other in terms of what they followed.

Yup

I’ll have to go back to those videos. I haven’t seen some and it’s been a while since I watched. Just the latest one with the Ford 302 & a series of heads he tested. Baby small cam as well.


The 4.8/5.3 head flow ?
i believe it’s somewhere around 245 cfm, so it would be if a 273/318 came factory with something like eddy heads.
