have a 1973 swinger 318 built up, see garage page...
my fbo ignition system keeps frying ignition coils, and everything checks out. ive even went though mopars checks, and don form fbo's checks. no ballast resistor, direct 12volts... using his flamethrower coil, runs great for a while, then craps another one. I box is grounded? not sure, giving up, going to replace stock distributor with he fbo degrees plate installed and the fbo box with a mopar convention set up. just what to run. .... not worried about msd sparking anymore..
looking at the most inexpensive bolt In set up I guess. looking a tan orate box, mopar unit, stock distributors, and standard coil with ballast resistor... which coil 13.5 or 3.0 ohm coil?
and any particular brands coil work better? also would a stock reman distributor or one with mopar advance springs be better over all, the car is built up 318 0 decked, 340 cam , headers, high rise intake , 600 sfm carb etc.. 3.50 gears.., oh and a PTC 2400-2800 stall converter...
 
Don't sleep with easy women. If she didn't make you work for it, stay clear.

I didn't read the post, just the title. Hope that helps out.
 
Maybe you just need to relocate the coil upright and away from heat. My oil filled one did not like to be mounted on top of my aluminum intake manifold. When I moved it to the fender it worked fine. I didn't like having the coil on the fender and bought an epoxy filled one, mounted it on the intake manifold and haven't had any issues with it there.
 
How is the coil mounted and are you sure it can be mounted like that? Not all coils can be upright or later down.

Member Jonnypace from Pace Performance has inexpensive distributors. I have a ready to run unit. 2 wire hook up and the 3rd wire is for a tachometer. Under $200 delivered.
 
Epoxy coil mounted on fender. Not hoizontal. Not vertical. Mild 45 degree angle. Rubber insulated for vibration.... Does the coil need to body grounded in the coil bracket?
 
I didnt think it need to be.... Just checking. I believe is the fbo box once gets warm. But cantt prove it. 3 coils now. Just ready to start over.

I've been in the same boat. You think you are changing the right part, but in reality, the bad part just cooled down in the time it took you to change the part that was never bad.
 
Hey Josh, have checked the voltage at the coil with the key in the off position? Should read Zero.
 
I had a similar problem with the solid state coils. I am pretty sure they were MSD.
I tried 2 of them and neither one lasted over 3 miles. But the canister coil by MSD has worked perfectly
