Some 5.9 roller cam help from y'all please
The factory .410 cam is a turd in more ways than one, first is it leaves a bunch of torque on the table all while getting crappy mpg.
I would suggest a cam we have that I worked with Jim at Racer Brown to design. Unlike hughes and most big cam guys, we dont use a split duration, we feel its not needed in smaller cams with magnum exhaust ports.
By the sounds of what you said, I would recommend 212*@.050" with .510 or .520 lift. This should be ground on 110 for carb. If you want it in a regrind, it would have to be turned on a GOOD 5.2 core with only 112 LSA as the 5.9 cam is too small to get that our of the .410 core.
We sell regrinds from Oregon for $179 but they are our own proprietary grinds they wont grind for anybody but us as we own the "card".
Look us up online, call or pm for more info on magnum roller cams....we have been working with them since magnums came out.
The hughes 1824 would not be a good choice as it peaks too high and doesnt make good torque before 3000-3500 rpm. You want torque as close to 2300-2500 as possible to get good mpg and power with taller gears and freeway driving.
Lift is GOOD!!!
Run something in the 210ish range and 500-520 lift and cut it on a 108-110 LSA. No need for a wider LSA on such a short duration camshaft. It's going to idle fine. The stock 1.6 rocker ratio works well here.
You already have a valve spring that will hold up. No crazy parts required.
Ok I'm going to answer you both at once here.
FIRST, thank you so much for all the info (I lOVE info) :D
Now here's the deal and my possible solution.
The EQ heads out of the box only support a max .470 lift (bummer):D
Stock magnum cams have about .410 so there is a little gain there.
In order to do anything usefull about that I would have to change to a longer stem valve, with the accompanying retainers locks and springs, and I am definitely not doing all that for .030-.040 added lift. (which most available hydraulic rollers cams are .480 and above.)
What if I were to get a good torque grind cam and simply have them take some of the lift off to about .460 and a LSA and duration to get what I want out of it, but at a slightly lower lift?
That would get me everything I want without having the huge expense of re valving brand new complete heads wouldn't it?
That I could get down with if there isn't some reason I don't understand yet that it cannot be physically done.
Seems a simple solution even with my limited knowledge on cams and profiles.
Thanks again guys, as I know this must get old after 10,000 times. :D
