I was thinking about putting an MSD in my 5.9l. I was just wondering who has put them in and if its worth it. And the procedure of installing it. Thanks for ANY info.

 

On a stock truck not worth it, I even know of a few guys with 408s on a stock ignition

 

Quicker starts, smoother idle, slightly better throttle response up to about 3K RPM..... you don't get any more power though, nor does it help fuel economy.

I had one on my Firebird..... but, aside from what's listed above, there wasn't really any difference.

 

I have a 408 on stock ignition.

I don't think the msd would be worth it.

 

have a full MSD6A in my truck, box, coil, big wires and everything....seems to be mainly for looks under the hood to me lol....didnt notice anything spectacular besides like HeyYou said i did notice a steadier idle thats about it....relatively easy to hookup thought if you wana do it follow the diagrams they give ya with the setup
