O.k., I just order a custom roller cam for my 'Cuda's 408 Magnum with matching valve springs with ProRoller 7 way timing chain set. I took some of ya'lls advice. Thanks for all the help!
Going to a pro and getting a custom part just for your set up and intended useage is simply the best way about things. I'm sure you'll be happy.
You can read suggestions on line a gazzilllion times. Unless someone knows or you know something about cams and there dynamics and effect etc.....
It's close to kindergarden kids yelling out answers.
