Thanks for all the info about the headers ,really helpful thank you all . My second question was some one around " here" ( I live 5 minutes away from KRC performance) told me that if i ever wanted to run a cam that was healthy in size that i needed pcm from at least a 96 ram that was OBD II instead of OBD I in order to run a programmer to tune it maybe like a SCT . I was wondering has any body ever heard about this or even done it . I guess if i replace the pcm what do i do with the old style data link connecter ? Can i change the data link connecter with the newer one with ease so the SCT tuner will plug in ? I dont know. I do plan on doing other mods to it not just a cam, like the headers that i mentioned earlier,kegger mod ,throttle body mod and doing some head work and true dual exhaust What do you guys think about it. It's still just a 1995 with a 5.2 . I just want a cam that you can really hear and know it's in there ....

You cant just swap out the PCM, (so far as I am aware, going on GM experience here) You would need the entire wiring harness out of the donor vehicle, along with the PCM. One out of a manual trans truck would be best, then you could still use your 46RH, and not have a solid check engine lite.

I think that the dash gauges are also controlled by the PCM..... so, the dash would be necessary as well, maybe.......

You CAN reprogram your OBDI computer, it is just a tad more convoluted....... involves swapping out the chip in the ECM. Various companies offer custom chips.... but, you pay a premium for them, and for the cost involved, you can pick up most of the equipment to do it yourself, and burn as many chips as you care to.

 

Do you know any of the companys that allow you to do this chip burning for the older pcms
