I have a MSD Street Fire New for sale on Craigslist I also have a MSD Blaster SS coil to go with it. Send me a PM or email to mguzinski@gmail.com I know it's not the forum to list stuff for sale but...
I have run these before and they install pretty much like any MSD ignition. Here is the MSD site and you can download the Installation PDF on it too: http://www.msdignition.com/Products/Ignitions/Daily_Driver/5520_-_Street_Fire_Ignition.aspx
They work real well on street cars. I don't race so I'm not sure how they work on the 1/4 Mile. I'm guessing just fine.
