https://www.skspeed.com/msd-9254-ig...distributor-wires-coil-chrysler-273-360/ is the kit I got and the cheapest I've found. Only bad part is it doesn't come with a crank trigger kit. It works well for the money, wired right into all my stuff. Really fought back and forth with either the Grid or the programmable 6. If I was going crazy with my motor or messing with a two step a lot, I would have gone with the Grid. For all I need, even with nitrous, the programmable 6 works just fine. The MSD 7 is a good box, but I've had to repair way too many through the years and fight with some crazy cut and spliced in stuff to go with the 7. If you do decide to go with any programmable, make sure it's mounted somewhere you can get to it easily to plug into and a laptop with a serial port to make life easy.

Most are spraying one big kit and using a progressive to control it. Less complicated than multiple systems.

Monte Smith told me years ago to use a Holley Ecu. Even with a Carb. and now thats what i have. IF you think about it the Holley ECU you can use coil on plug, and have data logging as well as a great nitrous controller. The possiblities really are endless. You can control anything and with a nitrous car on the street you will want a lot of control. You can program dump valves and have crazy accurate control over timing with no fear of rotor phase etc. ITs the best you can get, and it condenses everthing into one unit. No seperate nitrous controller, data logger and ignition. PLUS you get free software updates from Holley. The new V6 has some awsome features for nitrous contol and the dump valves. Take a look and youll see how in th long run it will be way worth it.

Which Holley ECU are you referring to ?

I have to admit I need to do some better research abs the reason why I asked before I bought anything. This is some great info!

I don't have anything so I will need a complete compatible system so I am looking for recommendations on distributor, ignition module, wires etc. Also, I will be using a transbrake

This is a street/grudge race '70 Duster

Thanks !

I can answer all your questions and provide you with whatever you want. The Holley is the best system to use today for the reasons already stated. I remote tune cars every day, literally, (I tune on four different systems), and the Holley usually comes out on top without adding third party products. Check out my website fastmanefi.com and for sure if you're on Facebook, because that's where I post my recent tunes almost every day.

n20mstr was kind enough to give me some info through messenger and I gotta say the technology being applied to these systems is more involved and intimating than I imagined. I will sure check out your social media !

If I was building a grudge car this is the one box I would use, It would replace your ignition box, 2/3 step, launch retard, your delay box, your bump box, your boost controller, your nitrous controller (wet or dry) allows you to run duel fuel with a cheap GM sensor. Oh and it’s a killer data recorder, if you need a gauges/dash then a $125 android tablet. I am sure I am forgetting a few things, but one thing for sure it has a steep learning curve. Oh one more thing, it has traction control.

I am a big MS3 fan myself. I have run one of the DIYAutotune kits that required assembly(MS3X) for 5 years now and it has been awesome. I like the look of the Holley stuff and the software seems pretty nice but I have thousands of dollars less into this than I would have spent for a Dominator ECU.
