This truck is getting to be like my house.. a never endiing fixing something to suit my needs situation. BUT, OTOH, I have no car payments to make, so I justify my expenses in that respect.

That said, I've read around the past posts and still can't decipher what type of ignition box I should go with. I searched Summit racing for the MSD 6A unit, which I'm not even sure I need, but couldn't find it. I'm ready to do a tune up (distributor cap, wires/plugs/fluid drain&fill/air filter - K&N drop in) and the thought hit me (after reading here) to change out the ignition module for higher spark. It is also my hope to fall on the other side of my current 9MPG! I figured on 13mpg given a sensible foot. She runs good, but there is a little 'miss' every now and again. You can hear it up under the hood, but you hear it a little better at the exhaust. My thought is that after the tune up, I should hopefully see a slight increase in mpg, especially after the filter/plugs/wire/exhaust combo.

Any real world applications on what you'd go with as far as the ignition box? MSD, CRANE, MALLORY, JACOBS????

I'll shop online for the best price(s).

Thanks in advance. My learning curve is getting a little rounder in the middle thanks to this forum. Whomever is responsible, my hats of to ya!

 

I would go with an MSD 6a with maybe a Durospark set up as a plug in emergency backup. ( I am using 3 MSD's and haven't had one fail yet). I just like redundent systems.

 

I have a MSD 6A on my Mustang and I've never had any problems. It does cover up alot of sins. I let my stock plugs go for 100K miles and even though they were at over .070 gap, the MSD kept the fires lit...
