need help in choosing ignition box and coil

[GhettoPop]

I'd like to improve the ignition of my 72 challenger w/ '70 340. I was thinking of adding an MSD box. What would be best for my application (street car)? I've been reading about the new MSD Digital 6AL Ignition Control (Part No. 6425).

I really like the new rotary dials for rev control. Anyone running one or have any options? I also want to replace my yellow 80's coil maybe with an MSD Blaster 2. Please give me your thoughts. Looking for a good setup and will consider other brands, thanks.

Cool! First time I had seen the new style MSD 6AL box. I like the adjustable feature.
 I have the one that is black and says Mopar on it. Works great for me! I mounted mine under the battery tray. Also using an MSD coil.
Every performance car I have ever owned I have put one on with no issues ever!

I'm going with with an ignition box, coil and distributor setup from the gentleman at 4secondsflat.com.  He's got a pretty impressive setup with rev control that fits inside a stock looking ECU.  I spoke with him on the phone for quite a bit and was impressed with his knowledge and products.
