What do you guys like for ignition upgrade

You would be getting rid of both the control and ballest I think, go to MSDs web site and you can look at the installation diagrams and see before hand how to install all of their products. Another option is theirs a distributor now that uses a GM HEI module and all thats needed with that one is a coil, I am considering it for my next build just to be different and I like the GM HEI ignition. Sorry I would post links but would have to go find em as my computer crashed and I lost em all.
Oh and another thing about MSD is you need to use the spark plug wire they reccomend, solid core vs non solid core as thats very important and can cause the box to fail.
