    MSD ignition

    Has anyone installed one and if so do you think it was worth the cost to upgrade. I have a 85 CJ 7 with a 258. The msd boxes I'm looking at are about 300 bucks. Any thoughts on this product and what if any differences you've noticed? Thanks.

    Can't speak to the MSD, as I just run a junkyard HEI. If I had had a factory motorcraft distributor, TeamRush would have been the way to go by far- cheap, easy, and better engineered. Regardless, I found the HEI to be more than enough ignition.

    As far as I can tell, MSD on an old 258 seems like it would be massive overkill. Aren't those things mainly for drag racing tuned small blocks? Just pouring in tons more spark energy isn't going to magically make your engine run better. Just my 2c, interested to see what the experts will say.

    The MSD or Summit CDI MultiSpark Ignition and the stock DuraSpark Distributor, with a good premium set of wires and the TeamRush Larger Cap with brass terminals is the BEST IGNITION you can put in your jeep bar none. No one can tell you other wise.

    You can get the MSD or Summit version for well under $200 actualy closer to $150.

    I have that set up and my I6 starts when below zero, wait 1 min knock off high idle and I can drive off. I get 23/24 mpg hwy in summer temps. And my jeep pulls from 600 to 4300 or so rpms very nicely. I can cruise at 75-80 mph and not even a hick up. I had a new 1973 Jeep, actually my family had 4 jeeps back then.... my33 yr old cj runs just as well as they did in the early, mid, and late 70's.

    Ignition is a great way to make the jeep run better. Other areas are CArb, Intake, Header/Exhaust

    I love MSD stuff for all my ignition parts. Always performs the best and is a great piece of mind.
