Going to go with the 5.9!!

this is my set up
5.9 Magnum Stock heads stock compression 9:1
A904 3000k stall
3.55/3.91 gears
Tube headers
Rpm Air Gap
750 3310 Holley
67 barracuda

Looking into the best camshaft trying to stay right under .500 lift aiming for 400hp @ flywheel

These are my choices I came down to Oregon camshaft regrinds

#1169 220@ .50 282/282 duration at .498/498 lift

#1408 224/230 @50 276/282 duration at .480/.480 lift


Really like the number 1408 grind the split duration probably will sound nasty lol

What do you guys think?

Now that I think about it, contact Hughes Engines and get their trick spring and lifter kit, which allows for more than 500 lift.
Check out Charlie Servedio on YouTube and scroll down to where he does work on Magnum heads. I myself appearing a video with him on Magnum heads and then later on sent in his heads to be ported and he shows the results of what can be done. But does lack And lift to achieve the minimum horsepower number that stated at 400 hp.
