NOT the usual cam advice...

Well, you said 'Not The Usual Cam Advice', so here goes......

If you don't have to pass emissions test but want to increase low end power, a fairly mild cam with the LSA tightened up will get you there.

This is Hughes' mildest factory roller cam for the 5.9 litre (360) Magnum truck engine (208 / 214 deg, duration @ 0.050" lift, 0.523" / 0.533" valve lift with 1.6 Magnum rockers)......

Hughes Engines

Standard grind has 110 deg. LSA and 106 deg. installed centerline. Ask Hughes if they will grind it with tighter LSA and ICL similarly to their 'Whiplash' series flat tappet design for 340 / 360......

107 deg. LSA and 102 deg. installed centerline.

You should notice a marked improvement in off idle and low end throttle response. You will need to install with valve springs matched to cam and if you retain the OEM EFI unit, will probably need engine management computer mods to match recommended ignition curve for the 'Whiplash' spec cams. Hughes has recurved Pertronics distributors for their Whiplash cam grinds...... Ask them for the specs and have your engine management computer reprogrammed to provide same advance curve.

There used to be reworked 2bbl throttle bodies fitted with larger throttle blades for the Magnum engines. That would help. Also, around 1993 - 1994, the Dodge truck engines had larger 2-1/4" exhaust outlets and head pipes. Later year Magnum engines are identical except they have smaller 2" exhaust outlets. If you don't have the larger outlet exhaust manifolds, find some and a couple inches downstream from exhaust connection, slip 2-1/2" tubing over the 2-1/4" and weld it up. Then run 2-1/2" duals with an H-type crossover (balance) tube and you should see a noticeable improvement in performance. And again...... If you don't have to do emission testing where you are...... Can the cat and when reprogramming engine management computer, set it up to run without the cat.

Good luck with your build,
