FBO or MSD what do you use?

The best ignition box by far, for a Race/ Street motor is the (MSD digital 6). It gives you the most bang for the buck and is totally adjustable. with this ignition box you can lock your distributor up and let the box do the initial 20 degrees on its own. It also has a adjustable rev limit ,no pill, and two adjustable rpm activated switches for NOS or any other use such as launch control. All out race use the (MSD digital 7 ). I have use (MSD 6al's) also with no problem. I just found it easier though, when using the ( digital 6) to let the box do the initial instead of me closing up the travel in the distributor. Mopar distributors are good ,but the latest version with the adjustable timing travel is better. On the old distributors you have to weld up the advance slots to achieve the proper travel for your initial 20. The slots are 1/2 inch closing them up to 3/8 gives you approximately 20 degrees of initial. The new distributors are totally adjustable using two torx head screws, Mopar finally figured this out after 35 years. When I first started eliminating the vacuum advance's on the factory distributors. I would hunt a lean burn unit and use the solid magnetic pick-up plate and the vacuum canister cover , this would totally eliminate the vacuum advance for easier access to the hold down bolt. Eliminating the vacuum advance is a must on any motor with a the installation of a signifantly larger Cam shaft . Vacuum is changed with the overlap of larger cams and the advance is no longer achieving its economic purpose .That is all the Vacuum advance is for “Economy“. When ever you hear a car with a big cam and an automatic, with a factory advance they sound like and old tractor pa-plut pa-plut pa-plut. A properly tuned distributor and mild converter there should be little rpm drop when put in gear and the motor should sound like horses in gallop , Chrysler distributors are not good for over 7000. They have bushings and are not balanced and some of them do go into a static misfire. MSD distributor's are a better buy if you are going over that RPM range because they have precision bearings and are balanced. Otherwise stay with a factory type, tuning parts are easier to get and cheaper. All in all the best way to go for the street is a Stock new version adjustable friendly distributor and a MSD 6al control box with a blaster coil. This is only my opinion from what I have used and what is easily available at parts stores. You will notice a difference over the 40 year old ignition system from Chrysler with any newer ignition you chose, But the distributor is the heart , and if that isn't right your car will be a pooch . This is what works for me. Any more info needed I will try to answer. Steve
