Bought 5.7 hemi/nag1 out of a cop car. Some questions.

dustyaman said

First off Happy fourth of July everyone!
So long story short I sold my 360 and 727 and bought a 5.7 hemi/nag 1 setup out of a cop car that had 74,000 miles on it. Got a great deal for it that I couldn't pass up. I've already bought most of the swap parts for my 74 duster for it. My question is instead of having to spend 1500 dollars for a new cam for it to get rid of the MDS, can I just buy a tuner like a Diablo and just turn off the MDS? Or is that not possible. I know sublime technologies sells the wiring harness that comes with a ob2 port. So I'm just trying to figure out if that can work. Here is a picture of my car and the hemi.

If you plan to buy a harness from Sublime (Great company btw) you're more than likely buy going to buy an ecm from them as well.. not sure if you're looking at the quick harness or complete.. either way, you'll need an ecm. The ecm will run you 400 bucks and if you have a core, take $100 off. Anyway, have Blake set up your ecm any way you like. You can have him set your fan on/off settings however you like, turn off mds etc. He'll just do it.

If you want to change to a non mds cam/lifter.. look for a pull out 6.4 non mds. I bought my cam and lifters for Hoopty, for a few hundy with 30k miles. Looked near new, no issues. The 6.4 cam is a nice "no tune" cam but you will need to upgrade valve springs and you may as well have the heads freshened up if you're going that far. You can get Mopar Performance springs for under $100.. but factor everything in. Someone to do the heads, cam/lifters, gasket kits etc. You don't HAVE to do all that and can just have it turned off by Blake.

This is the springs you would need for a 6.4 cam
