Working on a 95 dodge with a 5.9L gas motor and want to hop it up as much as possible without makin it run like crap. I want to put the crane 704121 cam in it and a crane double roller timing chain, headers, and upgrade valve springs to match the cam, maybe a mopar performance computer, and someday possibly a set of roller rockers. Wondering what all is involved in the intake mod, I can port it or whatever myself, just need to know what to do, and I want to know more about the mopar performance computer. Is it just a plug it in and go thing, or does it have to have a programmer or be programed? Anything special? Also how do I get ahold of one? Does anyone have mopar performance phone number? Can't seem to find it. Also does anyone know what I'lll need for valve springs for this cam? It's 204,208 duration @.050, 114 lsa, and .458,.467 lift. Also anything else I can do? Thanks for any help. Brandon.
