Which coil is best?

    I'm going to be overhauling my ignition system on my 1991 Suburban, and I'm not sure what coil I should go with. Of course I want the hottest coil that will give me the best spark and I'm leaning towards MSD, but even in the MSD line, I'm not 100% sure which is the better line. Here's the 2 coils I'm looking at currently: http://www.summitracing.com/parts/MSD-8226/ and http://www.summitracing.com/parts/MSD-5526/ . Using a "you get what you pay for" methodology, I'd say the Blaster coil is better, but I'm not sure.

    I'm just looking for the coil that will throw the hottest spark with the longest spark plug gap I can muster. I'm open to suggestions for all brands, but it must be a drop-in, IE no MSD 6AL boxes or the like. An ignition box may come in down the road, but definitely not now. Any suggestions/opinions?

    @Crawddady, so my experience with ignition coils, wires and plugs is... when I used what I thought was higher end after market, always seemed to let me down. I will always go OEM.

    Now it's been a long time since I had to do my own ignition work and if I need some for my 2000 Impala it will probably be OEM. Just My humble opinion, and I'm sure there are some real good after market stuff ...

    Either one you want. MSD is good stuff. Ive had tons of items from them over the years and only had a few go bad... some of which they covered and fixed/replaced.

    The main reason I'm upgrading the coil is so I can widen up the plug gap and advance the timing to get more power and fuel mileage out of it. I'm basically mirroring what the Bronco community calls the "sixlitre timing bump" as seen here: http://www.fullsizebronco.com/forum/showthread.php?t=63592
