Fouling plugs. Jacobs Fc-1000 or LS1 Coils?

I'm running bur9eq's at all 4 plugs. I'm fouling plugs every 2 months or so. Car starts bogging and bucking pretty bad.
Mods:
88 TII
Haltech E6x
720/1680
Streetport
Stock igniton
etc
So I'm looking for a little boost to help burn the fuel a bit better and prevent fouling so quickly.
I found some good things about the Jacobs Fc-1000 on a search and am pretty sold on that. I like how theres little wiring and all I have to do is mount the box in line. No messing with haltech or anything.

Ls1 coils? I've made about 327 hp to the wheels. I don't really need any more power, I plan to get rid of the car in the future so I'm reluctant to do the Ls1 coils since i have to mount them, run more wires and change some haltech settings.

So I wasn't sure which route I should go if i don't plan to make more than 400 hp. I don't want to go over kill. but the prices for each are comparable so I wanted you guys' opinon.

Thanks

Lean it out more?. The stock ignition system should be plenty adequate for the kind of HP you're making. I'd look elsewhere for the solution to your problem and leave the coils alone.

My system consists of four MSD blaster coils with my Microtech LT10s, but that was because i preferred to do that than modify the stock coils, they were not a necessity. If you want to upgrade your ignition system, go for it, but you could just improve the tune of the haltech.

Yup-my thoughts exactely. You've got too much injector to start with. People have made way more power than what you've got on bone stock coils.

Good stuff guys. I knew I needed a retune but wasn't sure the priority of needing spark or w/e.
Leaving the ignition alone it is. I think its my idle afr thats taking the most toll on the plugs. (11/12) It doesn't like to idle smoothly on anything else.
Thanks for the tips guys!

720/1680 is what I'm running for my 400+ build, you probably could have gotten away with 720/1000

Looking back I should have. When i ordered them i didn't know what exactly I wanted to do with the car power wise so I ordered something that would be more than sufficient.

If you fouling the plugs, you either have the wrong temp plugs or the mixture is off on the tune of the Haltech
